Hi Mike,

It depends which engine and year you mean. Here are a few examples:

o 1.6 petrol - 2003 to 2005 - 80,000 miles (128,000km) or every eight years

o 1.7 CDTi - 2010 to 2012 - 100,000 miles (160,000km) or every six years

o 1.7Di or 1.7 DTi - 2004 to 2005 - 100,000 miles (160,000km) or every ten years

o 1.8 petrol - 2003 to 2010 - 60,000 miles (96,000km) or every six years

Hope that covers the model you're interested in

Hi John,

To be honest, it's a little hard to tell. The A3 Saloon hasn't been out long enough for us to get a solid handle on its resale values but we can work from a couple of basic assumptions:

 1. Yes, diesel is currently more highly valued than petrol.

2. That won't always be the case - now that the mad post-2008 scramble for diesel has subsided buyers are starting to get wise to the value of petrol power again, helped by improved engine tech.

3. An Audi, any Audi, will likely have stronger residual values than most other marques so you're already ahead of the game.

So I guess the answer is yes, your depreciation will be a little sharper on petrol than on diesel but I suspect it won't be by very much. Fret not and just enjoy owning one of our favourite current cars.

Hi Martin,

I'd say you're looking at a trade-in value of between €5-6,000.

Hi Eitvydas,

The first generation A-Class had shockingly poor reliability and while the second generation version was an improvement, we'd still be a bit wary. Electrics and suspension are your biggest areas for problems so check everything over carefully and don't even think of getting one that doesn't have a full and complete service history. Apart from that, they were also a little odd to drive - feeling rather like a gigantic shopping trolley in their vague and uncertain way they trundle along. Also, basic versions came with no air conditioning and had rubbish ventilation so hot days are a bit of a chore.

Hi Bryan,

The fuel gauge should not visibly go down over such a short drive, no matter how fast you're going! If there's a fuel leak then it's a big one to cause that, so start up the car in neutral with the handbrake on in a safe location (in the dry preferably) and get out and look underneath for any signs. If there is one we recommend turning off the car and having it towed to a garage for a repair.

However, it may well be that the gauge or the sender unit in the fuel tank are themselves faulty and it could be an inexpensive fix. Either way you should bring the car back to where you bought it (assuming it was a trade sale and not a private one) and insist they accompany you on a drive so you can demonstrate the problem. If there's a warranty in place this kind of thing should be covered.

Hi Dave,

Really highly to be honest. Big, spacious, comfy and very well made. The S80 isn't as sharp to drive as a BMW 5 Series, but it's reliable and incredibly comfy. The only wrinkle here is that the FlexFuel engine isn't the best - it's thirsty and there's nowhere selling the biofuel for it anymore. Unless your mileage is low, it's worth seeking out a 2.0-litre diesel model.

Hi Annette,

I think your best bet could be to upgrade to a newer Mazda3 Saloon. The second generation 3 four-door is a really nice car - spacious, comfy and reliable, and if you get a 1.6 diesel from 2008 onwards you'll be paying half nothing for your road tax. 

Expert answer

Hi Eitvydas,

A bit, yeah. 75hp was never quite enough to shift the Golf's bulk. You're better off trying to track down a nice 1.6 petrol instead, or going for the ever popular 1.9 diesel.

Hi Barry,

To be blunt, you're going to struggle to get a decent diesel engined car at that price level. There do seem to be one or two diesel Peugeot 307s or Renault Méganes around at that sort of money but we'd advise serious caution before purchase - neither have a great reputation for reliability. 

Unless you're covering mega-miles every week, you would probably be much, much better off getting a tidy 1.4 petrol hatchback, perhaps a circa 2002 Toyota Corolla? Really solid on the reliability front, excellent fuel economy and affordable motor tax. It would be a much better idea than going all out for diesel but ending up with a less reliable car.

What do you think?

Expert answer

Hi Jemima,

It really depends on which model you're talking about. Assuming it's the all-new Qashqai launched this year, the 1.5-litre dCi diesel are in Band A2, costing just €180 per year to tax; the 1.6-litre diesel (manual or automatic) is in Band A4 at €200 per year; while the 4x4 Qashqai with the 1.6-litre diesel is in Band B1, costing €270 per year. The 1.2-litre petrol versions are also in Band B1.

Hope that's of some help
