Hi Sean,

With those options in front of us and no clue to each car's mileage and condition then we'd say there's a strong case for the Mazda6. It's significantly more spacious than all the other cars you listed for a start. That 2.0-litre diesel engine has plenty of grunt and is relatively economical, while the Mazda6 has a great reputation for reliability.

Hope that's of help

Hi Andrew,

First of all, the relatively straightforward stuff. There are less Titanium models around than LX and Zetec so it's worth a little more. Autos are quite rare as well so it's not easy to accurately predict the value. However, we reckon you could advertise it for €16,999 as a private sale (and accept a little less) and expect an offer as low as €13,000 in trade-in. Bear in mind though that you should focus on the cost to change if you're going down the trade-in route.

Your car is already at the high end of the mileage range for S-MAXs of that age and if you plan on continuing at the same rate then it may well make sense to change now before the car loses all appeal for dealers - as you've pointed out. 

Hope all that helps.

Hi Justin,

I'm sure you don't need me to tell you that the lower mileage car you can find, the better. All three models mentioned are suitable for the job, though there's a reason so many taxis are the Toyota Avensis. It's the one we'd veer towards. The BMW would be a nicer car than either the Passat or the Toyota, but once you start racking up high mileage its maintenance could get expensive.

Hope that helps.

Hi Patrick,

It does indeed have full-time four-wheel drive. It's called xDrive and in normal use the power is split 68:32 rear to front but this can be varied to as much as 100% rear-wheel drive.

Larger cars like SUVs are always a little harder on tyres, but the X3 is not unusual in that regards. It has a good reputation for reliability with no known suspension problems.

Hope that helps.

Hi Michael,

It sounds like this choice is down to personal opinion. The Passat has a better reputation for reliability, though the Insignia is not too shabby on that front. The creaking interiors affected early cars and you should be able to quickly check for it on a test drive.

We agree that the Insignia is a better looking car, though the Passat Highline has a great specification. Countering all that the Insignia's 2.0-litre engine is more powerful, if louder and less refined.

In summary, we'd probably go for the Passat, but regret it every time we see a good Insignia!

Best of luck - let us know how you get on.

Hi Lukas,

There are many different models of diesel Opel Astra, even for 2007. There were 1.3-, 1.7- and 1.9-litre CDTi engines that year, plus three-door GTC hatch, five-door hatchback and estate. Not to mention different mileages and trim levels.

The latest selection from Carzone.ie suggest a price variation of between €5,000 and €11,000.

Let us know specifics if you'd like us to help some more.

Hi Ann,

Our writer Kyle Fortune drove the new ML 250 CDI so I've passed the question to him for answering. This is what he said:

"The base 250 CDI engine in the ML is actually a 2.1-litre turbodiesel mated to a seven-speed automatic to best make use of the engine's torque and power spread. It works relatively well too, so long as you remember you're shifting quite a lot of bulk without masses of power. That said it's got a sizeable 500Nm of torque generated low in the rev range, so the ML 250 CDI is rapid enough in town traffic. It's only out of town - on a motorway slip road when you push it - that you'll perhaps be a bit underwhelmed by the performance. It's all about expectations though, and really, it's a credible performer.

As to the BMW? It's difficult to comment on a car that doesn't exist, but experience of BMW's small capacity turbodiesels does suggest that they typically over deliver on expectations - the 520d for example feels very rapid given its size and weight. How that will translate to the bigger, weightier X5 is questionable, though BMW is unlikely to release a product that's not at the top of its game. We've not heard anything about a 2.5d X5 (officially or not), but it's quite possible given the prevailing economic climate and the ever tightening quest for economy. Downsizing is common so it stands to reason that BMW might be considering it for the X5."

Hi Abdullah,

It's not the usual kind of question we get and obviously you should only do such things on a private piece of land! Assuming you've properly disengaged the traction control (you have to hold down the button for 10 seconds), put the transmission into manual control so you change gears with the paddles behind the steering wheel. Drifting is all about the initiation and without a mechanical handbrake or clutch you'll need a combination of power and momentum (depending on the model you have).

Until you're comfortable with it, it's best to start off slow. Approach the bend, brake so that the weight transfers to the front tyres, release the brakes and start to turn. As soon as you do, get on the throttle and be ready to feather it and add some opposite lock. You will need to be in a low enough gear for the engine's torque to overcome the rear tyres, but not so low that you run out of revs early.

This is only one way of doing it. There's no substitute for practice, so get yourself along to a Mondello Park test day and experiment in a safe environment - and never practise on the public road.

Final word: don't expect to be able to drift for very long if you have a diesel XF. Most diesel cars have a very narrow power band that makes them tricky at the best of times.

Have fun...

Hi Anna,

As you're doing double the average annual mileage, and it's on motorway, we'd thoroughly recommend the diesel. It should save you a fortune on fuel, though of course you'll have to pay more in annual road tax. The downside is that you're likely to find that the 2.0-litre diesels within your budget have high mileage on them already. Seek out one with a perfect service history and as low a mileage as possible - and get it verified by Cartell.ie.

Hope that helps

Hi Mick,

The 1.6-litre TDI engine has 105hp, which doesn't sound like much, but it's the engine's torque that matters more in the real world, and this Passat has 250Nm from just 1,500rpm. It's more than enough for the Passat in most circumstances and as all the performance is low down in the rev range you don't really change down to overtake.

Saying all that, if you plan on towing or you drive with a full car regularly you'll appreciate the extra power of the 2.0 TDI engines, but most people will find the 1.6 perfectly acceptable.

Hope that helps.
