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.

Hi John,

Nothing major to worry about although there are a few electrical glitches - the keyless ignition system (if fitted) can give trouble, as can the hands-free locking and unlocking (again, it was an option). There have been isolated reports of the 2.0-litre diesel engine cutting out unexpectedly too. Check the interior trim carefully as well - Mondeos often rack up big mileage and while the mechanical bits are sold, the cabins can suffer from abuse - look for collapsing seats or disintegrating trim.

Hi Sandra,

The only persistent issues with the Insignia are electrical problems that can effect everything from the door locks to the alarm system. Usually these are just minor problems that can be fixed, but occasionally the problem is in the wiring loom itself and that's a much bigger deal. Check and make sure all the buttons work and also check the boot area for any dampness - the boot seals can leak and allow in water. For a 2.0-litre diesel Insignia, I'd be disappointed if you couldn't get it to do 50mpg in everyday driving.

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 Brian,

Generally speaking, the Sedona should be as close to utterly reliable as is possible. A 2008 model will still have up to a year's warranty left on it, which is reassuring, and the only repetitive niggle we can find with them is that the electric sliding side doors can have a mind of their own and you will probably often have to resort to manual control. Kia dealers don't seem to be able to locate the source of the problem, for some reason. 

We have heard reports of a few 'Friday afternoon' cars that have had troubles with clutches, brakes, air conditioning and gearboxes, but these seem to be very rare indeed.

Hi Chris,

The thing to bear in mind here is that the engine rarely has to directly power the wheels; most of the time it operates (at set optimum speeds) to turn the generator and charge the battery pack. Other than that, when it does power the front wheels it's at specific speeds in particular conditions, for which we assume it has been calibrated. The addition of a CVT may well enhance the situation, but it would add another chunk of weight to an already heavy vehicle.

Electric motors don't need a continuously varying gear ratio to operate efficiently.

Hi David,

Not a terrible car but you could do better. The third generation Mégane atoned for many of the reliability sins of its forebears. It's well made, comfy and super economical. Make sure all the electrics work properly and argue yourself a good deal - Méganes depreciate heavily so make sure you're not putting too much into the front end.

Hi Deck,

There seems to be a bit of split in S-Max ownership between those who have solidly reliable cars and those who keep suffering annoying niggles. Electrical faults are surprisingly common, and can range from knackered windscreen wipers to a fault that drains the battery over the course of a couple of days. Other have complained of some loose-fitting interior trim, especially around the doors. Keep an eye out too for clonking noises coming from the steering, stiff brake pedals or the diesel engine cutting out mysteriously.

Expert answer

Hi Pat,

Yeah, electric window failures are depressingly common on most Renaults of that vintage. I'd say generally you're looking at a trade-in value of around €3,000 but you can probably knock another €750 or so off that thanks to the knackered windows.

Expert answer

Hi Brian,

Yes, but only if you get it checked very, very carefully. This was the model of E-Class that gave Mercedes a serious warranty headache and almost single-handedly undermined the brand's reputation for quality. Most of the problems (chiefly electrical issues) should have been ironed out by now but check to make sure all the various systems work properly and if it doesn't come with a phone-book's worth of service stamps and receipts, walk away.
