Hi Marc,

In general this car sounds like a decent, safe buy, especially as it has the reassurance of a full service history and a new NCT. Mercedes instigated a model update in 2006 so it would be interesting to know if your car is the last of the first generation of the first of the second. The updated cars are better all-round and feature more safety equipment as standard.

The early cars are known to have had a few electrical issues, with recalls in 2004, 2005, 2006 and 2008. None were major problems, but it's worth checking this car's details with Mercedes to find out if it was affected and if the repairs were done.

Other than that, the E-Class is mechanically robust, so just take the time to try every electrical switch and device for yourself.

Hope that helps

Hi Henry,

It's not often we get asked about the second-generation Fiat Croma. It didn't sell all that well as buyers didn't really know whether it was an MPV or an estate. However, it sounds like it could be an ideal candidate for your partner's needs.

The Croma majors on space, practicality, comfort, safety and equipment. The version you found has very few kilometres on the clock, which is always a bonus. Make sure you check that every switch and control is working though, as Croma owners have reported niggling electrical faults.

Our other piece of advice, if you like the Croma, is to look for a diesel version. The MultiJet diesel engines are strong and economical so would be better than the 1.8-litre petrol version over long distances. That said, the petrol engine is quieter.

Hope that helps.

Hi Damian,

The Scenic's problems are well documented. We're not aware of a good set of data from Irish buyers, but in the UK, the Driver Power Survey 2010 revealed that 20 percent of Scenic owners reported electrical problems and the car scored particularly poorly in terms of reliability and build quality.

It also depends on what model you are talking about. Look out for the following:

1999 - 2003 model: leaky sunroofs, broken wiper motors, automatic gearbox problems and oil leaks.

2003 - 2009 model: ignition coil, auxiliary belt tensioner, timing belt, alternator, fuel filter, crankshaft sensor, oil leaks, idler pulley, water pump, thermostat, catalytic converter, door seal and sunroof leaks, problems with the key card and battery faults.

We're not saying that every version will have all or any of those problems, but these have been reported by previous owners.

Hi Michael,

We found an identical car to yours with the same mileage for sale for €8,950. You probably won't get offered that much as a trade in, but you could have an overall budget of about €17,000.

In terms of the Mazda6, that is a really good car and there weren't too many of the diesel models sold initially. The petrol models sold in higher numbers initially because they were cheaper than the diesel ones at the time.

You would pay about €16,950 for a 1.8-litre petrol model like the one we found here at a SIMI dealer.

Here is another excellent one in Cork, for €16,900.

Diesel models cost quite a bit more, with a 2008 model at a SIMI dealer costing closer to €20,000.

For the mileage you do, you could get away with a petrol model without totally breaking the bank and you certainly won't save in fuel costs by spending the extra on the diesel model. Granted, road tax will be higher on the petrol.

You could probably get into a 2008 Passat BlueMotion with your budget and that too would be a good car. Yes, I've heard of some occasional issues with the latest Passat, such as a problem with the power steering and with the electric parking brake, but they have been pretty well dealt with by Volkswagen.

Hi Michael,

Sorry to tell you that the 156, as much as we love them, have not proven to be very reliable. The Driver Power Survey (carried out in the UK, but usually relevant to the same cars sold here) continuously ranks the Alfa 156 near the bottom for reliability. On closer scrutiny the much talked about electrical problems seem to be niggles rather than serious issues, though blown head gaskets and water leaks have been reported too.

As with any second-hand car, go for the example with the best service history, and make sure with the 156 that it had its 60,000-mile service done at the right time.

Same advice with the 146 really with regards to service history. It's especially important that it has had regular, on time timing belt changes so if there's no history showing this then look elsewhere. Smoky engines are a giveaway to expensive future bills, as are groans and creaks in the suspension. As with the 156, electrical niggles have been widely reported, though it seems that some cars have them and some don't...

In summary, if reliability is the most important aspect of this car purchase to you, then we'd not recommend either of these cars, but if you're already sold on the idea of one of these Alfas then we'd suggest you veer towards the 156.

Hope that helps.

Hi Ray

I understand that your Corolla saloon has 68,000 km (42,000 miles) on it. Prices seem to be fairly consistent for them and you should probably expect about €8,000 - €9,000 as a trade-in, which isn't bad because your mileage is quite low.

Your budget is €4,000 and you need a seven-seater and you want something that is going to be reliable, comfortable and safe. I understand that you are being asked to spend €3,000 with your own car for a 2005 model and €4,500 for a 2006 model Scenic. This seems a little steep to me and steep to our Renault advisor. Also the Scenic, as it ages doesn't always stand up in terms of reliability. 

However, if money is an issue, I would be inclined to go for a petrol version of the Scenic, which can be picked up for half the price of the petrol models.

However if you want something reliable I would think you might stick with Toyota and get a Verso. 

Something like this 1.6-litre petrol model would be a super buy and it is from an SIMI dealer.

Hi Karl, I have stuck my neck out already this year and said that I thought the new Peugeot 5008 was the best car in its class and for now I am sticking to that.

The 5008 feels well built and crucially is incredibly well priced and well equipped too. The 5008 starts at €26,870 for the SE version and, when you compare this to some of its key rivals, it's excellent value. There is only one engine choice though, which is the 110hp 1.6-litre diesel (HDi). 

For €28,995 you get the SX, which gets cruise control, front fog lights, 16-inch alloys, sun blinds in row two, electric windows all round and a leather gear knob. 

The new Ford S-MAX starts at €31,495 (not sure why Ford's site says it starts from €29,995 - it is confusing), which is a lot less than it used to cost and the updated model is pretty impressive too. You can have this with three different outputs of 115hp, 140hp and 160hp. The S-MAX is a better driver's car with better handling, but 5008 ticks all the boxes in terms of size and space and crucially is better value.

If you are sticking to a budget then I would say go for the Peugeot 5008 SE. However, since you seem to have narrowed it down to two cars, you should probably test drive both and decide for yourself.

Camshaft sensors in most cars are really easy to change, though as with all things under the bonnet we'd always recommend that you bring your car to an expert unless you know what you are doing.

In most cases this work would take 10-15 minutes.

Without the car in front of me, or a workshop manual, I would hesitate to give you more precise instructions, but usually the sensor is held on by just one or two bolts and an electrical connector.

Assuming that is the case, remove the bolts and connector and reverse the procedure for the replacement sensor. Be careful that you do not damage the new sensor.

You should be aware that some cars may need their on-board computer (the Engine Control Unit - or ECU) reset following this operation. Ideally this would be done by a main dealer or garage with the correct equipment.

What has lead you to diagnose a problem with the sensor? (You can reply in the comment box below)

There has been a lot of debate about the benefits of hybrid cars, but few would disagree that they are a step in the right direction. The principle of the current crop of hybrids, for those that don't know, is that a standard petrol engine is combined with an electric motor, with the result being better fuel consumption and lower emissions. The original Toyota Prius was the first mass-produced hybrid on sale and Toyota has just released the third generation of the model and it promises to be more refined and cleaner than ever.

There are other alternatives such as the Honda Civic Hybrid, which isn't bad either, or the Honda Insight, while at the top end of the scale Lexus does three hybrids, the GS 450h, the LS 600h and the RX 450h. In the case of the Lexus hybrid technology it's as much about giving the cars higher performance as it is increasing efficiency.

A hybrid is cleaner in so far as official emissions figures are very low. The Prius emits less then 90g/km, which will make it the cleanest petrol car on sale in Ireland. In some cases you could get better fuel economy from a diesel engine though.

With a budget of €40,000 you could easily get into the new Prius when it arrives in October, as the car is expected to cost about €28,000 and this will be a very cheap car to run, so it seems the natural choice. Bear in mind that even cleaner technologies will arrive soon, including those in the Opel Ampera and even a new plug-in version of the Prius.
