Hi Patrick,

I've always had a bit of a soft-spot for the current C5. No, it's not as sharp to drive as a Mondeo or Passat, but it's a lovely, comfy car with tremendous long-haul refinement. Pick of the bunch is the 1.6 HDi diesel model and you should get an easy 50mpg out of it.

As for faults, check for a chuffing sound from the engine when it's running, as that could indicate that the fuel injectors are in need of replacing. Make sure it's had a cambelt change and watch for diesel particulate filter warning lights, which indicate that it needs a good long run at high engine speed to burn the collected diesel soot out of the filter. Suspension problems are quite common - usually worn ball-joints or bushes. Other than that, they're pretty solid.

Hi Jack,

Depends — do you want one? If so then yes. It’s a decent car, well-built, fine to drive, roomy and reliable. Just make sure you get one that’s been looked after properly, is all.

Hi Alan,

The Sport only has minor trim differences on the Passat — it’s not a separate model, just a slightly sportier-looking body kit and some extra equipment on the inside. Essentially, there’s no difference at all.

Hi Stephen,

At the time, they were very reliable and solidly built, but I’d be slightly wary now, especially if it’s a car with patchy service history. The diesel models develop problems with both the injection system and the air mass sensor, while the 1.6 petrol was underpowered and consequently has to strain to push the car around, leading to excessive wear and tear (especially to the front driveshafts).

The good news is that there aren’t too many fiddly electronic system to go wrong, but check the car over very carefully and if there are too many holes in the service record, walk away.

Hi Kevin,

As discussed via email, as you knew from the outset that a six-month warranty was included and you never queried it then there doesn't appear to be be anything you can do after the matter. It's up to the individual seller/dealer/garage how much of a warranty to offer I'm afraid.

Hopefully your car will prove reliable in any case.

Hi Catherine,

OK, so what you need here is something spacious (kids, even just the one, take up a heroic amount of space, as you know), something economical for all that annual mileage and something comfy so that your buttocks survive all that mileage. I think you should stay with the current rough size of car, as some of the best bargains can be found in the mid-size saloon segment.

First up is a Volkswagen Passat. Ideally, you'd get the 1.6 TDI BlueMotion version, a car in which we once managed to drive from Galway to Glasgow and back on one tank of fuel. Or, what about a Ford Mondeo? You'll easily get a 2.0 TDCi model for that money, and there are very few cars quite so comfy on a long journey. Even BMWs and Mercs can't always match the Mondeo for seat comfort.

Of course, if you fancy the high life, and are prepared to compromise on space a little, then there's the BMW 3 Series. You'll get a 320d or 318d for that kind of budget, but shop around to make sure you get one in a dark metallic, with leather and preferably an automatic gearbox.

Finally, there's the Mazda6. Bit of an unsung hero of this segment, it's brilliant to drive, spacious, good looking and you should be able to track one down with Mazda's excellent 2.2-litre diesel engine under the bonnet. Reliable as it gets, it should chomp through your annual mileage with nary a worry. Find the even more handsome estate version if you can.

Hi Pierce,

Prices for 2007 Passat diesels are currently hovering between the €10,000 - €14,000 mark, so expect a bid of around €10,000 if you're trading in at a dealer. Mind you, the high mileage of your car will knock that back a bit more, so don't be surprised at bids of below €10,000.

Let us know how you get on.

Hi Martina,

Clearly mileage, condition, specification and history will play a big part in the value of any car. The 2007 Passat powered by a 1.9-litre TDI diesel engine fetches anywhere from about €7,000 to over €12,000 as there are so many different examples around.

Hi Bryan,

Trendline is a the most basic VW trim level, so it’ll be pretty bare inside, and lacking for ‘toys.’ Comfortline is a step up, and on a model of that age should include such things as climate control and cruise control, amongst other niceties.

Beware though — that 1.6 FSI engine was not the most reliable thing that VW ever made, so make sure it comes with a full and complete service history. As for servicing, generally a VW will indeed be more affordable to service than one of the premium brands, but if you’re interested in buying a BMW or Audi then you can bring your servicing costs down a lot by going for a good independent specialist rather than a main dealer.

Expert answer

Hi Shan,

Around the €7,000 mark is a good estimate. It'll depend on condition, equipment and which trim level the car is in of course.

Hope that helps.
