Hi F D,

There are some small differences. The three-door A3 sits on 2,601mm wheelbase, while the A3 Sportback (the five-door hatch) has a 2,636mm wheelbase so there's a bit more room in the back. The A3 Saloon has a wheelbase that's fractionally longer again, at 2,637mm, but that's a negligible difference, so really, it has the same rear seat space as the Sportback. There's a significant difference in boot space though. Both hatchback versions come with a 380-litre boot, or a 340-litre one if you opt for quattro four-wheel drive (the rear diff has to go somewhere, after all). The saloon has a much bigger boot though, at 425 litres for the front-drive version or 390 litres for the quattro version.

Hi Simon,

Not much is the short answer. Cars like these are very, very thin on the ground and only appeal to a tiny, specialised audience, so while in later life their depreciation will be catastrophic, at only a year or so old they'll retain a good chunk of value. I'd say don't expect much more than about 15 per cent off the new list price.

Hi Liam,

The official figures for that model were 34mpg or 8.2 litres per 100km on the combined cycle.

Hi Gavin,

I'd have to say nope. It's not very big inside and it has needlessly heavy steering that makes manoeuvring in town a chore. 

Do you really need an SUV? Why not consider a nice estate? BMW's own 3 Series Touring is a belter. Or, for your budget, you could probably stretch to an Audi A6 Avant. Track down one with quattro four-wheel drive and leave all the front-drive SUVs standing when it snows. 

Or, if you're determined on the SUV front, consider one of the following: Honda CR-V, Volvo XC60, Hyundai Santa Fe or Mazda CX-5.

What do you think?

Hi Keith,

Depends on condition and history of course, but I'd say between €5,000 and €5,900 is a good ballpark. We've seen one on for €11,000, but frankly that person is out of their head...

Hi Mícheál,

This kind of thing is always difficult to analyse from afar so unless you're used to DIY on your car it's best you take it to a mechanic you trust. It sounds like the catch on either the lock on the door or the B-pillars themselves is not aligned properly. The lock may be damaged too of course.

Let us know how you get on.

Hi Sunil,

I'd say the Audi Q5. The GLK is still left-hand drive only (or did you mean the smaller GLA?) and pretty ugly. While the BMW X3 has evolved into a really nice car, for my money, the latest round of updates to the Q5 have just nudged it in front. Slick to look at, slick to drive and very comfy inside. It's a belter.

Hi Danielle,

About €7-8,000 - maybe a touch less as a trade in.

Hi John,

OK, there's a balancing act to be done here. There's no doubt that the CO₂-driven diesel stampede since 2008 has driven up the values of second hand diesel cars and driven down the values of their petrol equivalents. However, that is starting to change, and cannier buyers (helped in some part by investigations and comparisons by the CompleteCar.ie team - blowing our own trumpet etc. etc.) have shown that the overall cost of buying and running a petrol engined car can actually be lower than that of a diesel, especially for those drivers on relatively low mileage like yourself.

In that sense, I'd be well in favour of getting the petrol one, but there is a caveat to that - the A4 is very much a business market car, and therefore most of its prospective buyers, new and used, will be expecting to see a TDI badge on the boot. If you're buying on a lease or a PCP with a guaranteed future value, then that's not such an issue, but the answer is yes, you could well lose out a little on depreciation over a few years. Probably not a lot, but it's a moving target at the best of times.

Can I suggest this? Instead of an A4, have a look at the A3 Saloon. It's admittedly smaller, but it is also prettier, better to drive and good enough to win Family Car of the Year from the Association of Professional Motoring Press (APMP). It can also be had with the excellent little 150hp 1.4-litre turbo petrol engine and should be somewhat less sensitive to the diesel/petrol tug of war when it comes to second hand values.

Let us know which way you go anyway.

Hi Michael,

Right, the base spec is going to be harder to sell on again, so you're better by far going for the S line as long as you can live with the firmer ride. 

In terms of the difference between the cars in mileage and warranty - it's down to condition and history. If the 80k car is in as good nick, and has a full service history, then there's nothing to worry about and you can always buy an aftermarket warranty to keep yourself covered.
