Hi Darren,

It depends on the seat you’re using. Some seats need a separate ISOFIX base to attach to the latching points, especially the very first seats that newborns can go into.

That said, it could be the car — there seems to be some difficulty with that generation of A6 having been advertised across Europe with ISOFIX, but not having it fitted as standard in all markets. If the car was advertised with ISOFIX and you bought it on that basis, bring it back to the dealer and demand a retro-fit. If not, make a note of the car’s VIN number (it should be visible through the base of the windscreen) and call your nearest Audi dealer and ask them if they can help.

Hi Fergal,

In a purely objective sense? No, there’s nothing. Will you get an interior that looks and feels a bit classier? Yes. Will you get a badge that has a bit more appeal? Yes. Do these things really matter? Not to everyone. If you’ve got a Mondeo then you already have a well-made, comfortable car that’s good to drive. So upgrading to an Audi or BMW will get you… a shinier badge. If you want something that feels as good as the premium stuff but costs less, have a look at a Volkswagen Passat or Mazda6 as a potential replacement. The only area in which the German cars are quantifiably better is in resale value.

Hi Anthony,

It depends on the year of your current A6, but while there's not a huge jump in emissions by going for the V6 TDI, there is a big jump in price so it's certainly not going to be cheap. Others well worth considering are the incoming new BMW 5 Series with the 530d engine (or consider arguing yourself a good deal on a runout current shape model), the excellent new-shape Mercedes-Benz E 350 d or the Jaguar XF 3.0 V6 D. Test drives below to tease you further...

Hi Jim,

Nothing to avoid, in particular, but lots of good ones to try out. Start with a Mazda6 Tourer, or a Ford Mondeo Estate, or a Skoda Superb Combi. If you want to save a bit of money (but not compromise on space) go for a Skoda Octavia Combi, if you want something with a bit of class go for an Audi A6 Avant (pricey but the 2.0-litre TDI keeps running costs down).

Hi John,

The Mazda6 - it's the best to drive and the most reliable.

Hi Aiden,

That’s a good-sized budget so you should be able to get a good-sized car. In terms of car-vans, the best ones are the Citroen Berlingo and the Volkswagen Caddy Life, but both are noisier than a conventional car, and less comfortable over long distances. With that in mind, I reckon you need an estate – have a look for a Mazda6 Tourer, Ford Mondeo Estate or Volkswagen Passat Estate – or keep an eye out for the best of breed, the Skoda Superb Combi. All are comfortable, roomy and have frugal diesel options.

Hi Michael,

I’d avoid the pre-2010 Mercedes-Benz E-Class – it had no end of reliability issues. Your other two choices, the Mazda and the Lexus, make much more sense as both have excellent reliability. Both are also tremendously enjoyable to drive, and it’s worth keeping an eye out for a hybrid Lexus if your mileage is that low, and especially if most of your miles are in town.

Hi Valerie,

The problem is that you’re going to struggle in a premium-brand car to find the sort of rear-seat width that you need. The sad fact is that most sporty, expensive estates are designed around four passengers and the middle rear seat is usually an uncomfortable perch that’s often too narrow to comfortabley fit a car seat into.

So, I’d suggest you broaden your remit a little. Of the premium cars, realistically only the Volvo V70 and Mercedes-Benz E-Class are going to offer the kind of cabin space you need. If those are too expensive, look instead to the more workaday brands – Ford  Mondeo, Volkswagen Passat, Toyota Avensis, Mazda6 and Peugeot 508. You may not get the premium badge you crave, but you’ll get the interior room you need and at a much lower cost.

Hi Dan,

Right, I'm going to give you a couple of really safe options: Mazda6 or Toyota Avensis. That budget should see you into a 2008 model, and both are roomy, very reliable and pretty good (Toyota) or really good (Mazda) to drive.

Hi Mike,

Most average family cars will pull 750kg easily enough, and if you like Mazdas, can I suggest a Mazda CX-5? It’s one of the better SUVs out there, and the extra height might make it easier for your family member to climb in and out. Plus the 2.2-litre diesel should bring down your running costs a little.
