Hi Michael,

Well, the simple secret is to buy very carefully and don’t touch anything that doesn’t come with a full and complete service history. Old Land Rovers and Range Rovers are always a bit troublesome (although much less so than they used to be), but a Touareg should be a solid choice. Of course, if you want ultimate reliability you should just buy a Toyota Land Cruiser...

Hi Gerard,

Check the air conditioning to make sure it's working - that seems to be a perennial A6 weak point. Also make sure that the engine has had a regular top up of oil - they do get through a bit between services. Check everything electrical too especially if any of the warning lights on the dash are on. ECUs (Engine Control Units) are also a bit fragile so take a long test drive with lots of hard acceleration and check for any drops in power.

Hope that all helps

Hi Michael,

You've not mentioned whether you have the Superb or the Octavia, but either way our data suggests that the recommended service interval for the 1.6 TDI timing belt is 140,000 miles (225,000 kilometres) or every four years.

We'd suggest erring on the side of caution with timing belts always, especially on a car that you've not owned yourself from new.

Hi Kieran,

With that kind of mileage, you could probably look at saving yourself a bit of money by going for a petrol model - as long as the price gap between it and a diesel covers the fuel cost. Get your calculator out...

Of the cars you've mentioned, we'd go for a 3 Series. Few cars are as good to drive and it's the kind of thing you should own once at least. Check it carefully for wear and tear though and don't buy anything without a full service history. 

The only catch could be trying to find one that ISN'T a diesel...

Hi Sharon,

There are indeed others although the car has to be brought to one of a network of nationwide test centres for some. Or you could engage the services of a professional vehicle assessor, but that might be a prohibitively expensive option.

A good place to start is Cartell.ie

Hi Shirley,

Generally speaking, the Micra (especially the 2002-onward model, which is probably the best Micra there's ever been) is something of a gold standard for reliability, but there are a couple of small recurring items to look for. The immobiliser system can sometimes go a bit haywire and drain the battery, the seat adjustor cables can snag, the boot and door seals occasionally leak and if you hear a knocking noise from the steering on full lock it means the front suspension is out of alignment.

Other than that, cracking little car and it should give years of solid service.

Hi Mary,

Here's the official bumpf from the Department of Transport:

"If your motor tax expires around this time, and you have not received your motor tax renewal notice in the post, it is likely that you enrolled for the electronic service when your vehicle was last taxed online and have now received your PIN by email. Issue of your renewal notice electronically ensures instant notification of your PIN and easy access to the PIN when required. Please check the email address supplied with that online transaction to retrieve your online PIN.

"If you have lost or misplaced your PIN, have yet to receive it, or have recently purchased a vehicle and wish to retrieve your PIN, you can access the 'PIN Retrieval' link on our homepage, submit the requested details and your pin will be emailed to you if your vehicle is eligible for online taxing.

"In the case of the first taxing of a brand new or imported vehicle, the PIN is the last six characters of your vehicle's chassis number as printed on your RF100 form. You should have received your RF100 form either from your Motor Dealer or the Revenue Commissioners."

Hope that covers it?

Hi Bart,

We asked Volvo Ireland about this for you. Here was the response:

"The flexi fuel engines generally have shorter service intervals (10,000km or one year) and the system will say book for the next service if the mileage or engine hours or time have been reached. Even if the customer has not reached 10,000km, which seems to be the case, he might have reached the engine hours or time requirement for a service. I would advise bringing it into the dealership to get it serviced and make sure the correct oil and filters are used."

Hope that helps explain the situation.

Hi Eddie,

The Insignia is a fine car but you'll find it's not as spacious as your old Passat. Still, it's arguably more handsome and sharper to drive, but you have to make sure all the electrical bits are working properly.

As for the value of your Passat, you haven't given me a specific year but I'm going to guess it's around 2006-2007 in which case you're looking at around €5,000 as a trade in, but don't be surprised if you get offered less - cars with big petrol engines (even efficient ones) are forecourt poison right now.

Let us know how you get on

Hi Olivia,

The official figures for a 2008 Astra 1.7 CDTi were 56mpg on the combined cycle and 135g/km of CO₂. I'd say you could reasonably expect it to return that kind of economy in daily driving, assuming it's one that's been reasonably well looked after and serviced regularly. Oh, just to note though - that's the figure for the basic model with 15-inch wheels. Astras with wheel sizes 16-inch and above were officially rated at 55mpg.

Hope that helps
