Hi Jose,

Most timing chains don't have a fixed service life, but if it starts rattling or making any other untoward noises best to have it changed.

Hope that helps

Hi David,

I'd suggest flogging both cars and getting yourself into a newer Audi A3. They're comfy, sweet to drive, reliable and easy to sell on again eventually. Hard to go wrong with it, really. Lots to choose from so be fussy and make sure yours has a full service history and reasonably low mileage.

Hi Robbie,

It could well be a wheel bearing. Though it could just as easily be a tyre. Best bet is to bring it to a different mechanic to have it checked over.

Hi Andrea,

Yes, it's a cracking idea. While the old Santa Fe isn't as sophisticated as the current one (hardly surprisingly) it's still an excellent used buy, very reliable and nice to drive. 

A figure of 100,000 miles on the clock shouldn't be a significant hurdle as long as the service history is all up to date. The basic rule of thumb is that four-wheel drive and automatic gearboxes always add to the fuel consumption. The auto box on that generation Santa Fe wasn't the greatest so I'd say stick with a manual and 4wd is down to where you live - if you regularly need rough road or slippery surface capability it's worthwhile, if you live in town then not much.

Hi Ashasan,

I'm presuming you mean the 407 Solaire. They're better made than you might think. There are some issues with the 1.6 HDi engine though, including a sticking exhaust gas recirculation valve, sticky throttles and faulty injectors. Blown turbos have been known as well, but they're rarer. Cabins are better made than the French car norm, so if it's a bag of rattles, suspect that it's been in an impact. Many 407s will be ex-fleet cars, which is a good thing - it means that they will have been serviced on the button for the first few years.

Hope that helps

Hi there,

Incredibly reliable, seem to be consensus. So much so that there are simply no reported regular or common problems. Just do the usual checks for service history and condition and you should be fine. As for petrol vs. diesel, the funny thing with the Tucson is that the diesel version isn't actually all that economical compared with the petrol, so if your mileage is low and you can get a petrol one for less than a diesel one, it could be worth considering.

Hi Vittorio,

You've got it all answered yourself there. The BMW's overall residual value will indeed be slightly better, but, long term, the Mazda should prove to be much more reliable and rugged. Both are excellent to drive. The BMW's classic rear-drive chassis is slightly the superior, but the Mazda's muscular steering feel and firmly sprung chassis makes it one of the best front-drive saloon chassis around. 

Nothing major to watch for on either - just make sure there's a fully stamped up service history and check the BMW carefully to make sure that all the electrical bits work and that it's been topped up with high grade oil at each service. Both cars may have been driven hard by previous owners (many will be ex-fleet) so check carefully for thinks like uneven tyre wear or noises from underneath that indicate worn or out-askew suspension.

Hi Susan,

Nothing at all really, and if you're picking a Micra then you should be on a winner, reliability-wise. Fleet cars are often a better bet than private cars simply because their service history should be full and all major maintenance done on time and schedule. Will it have had a harder life than a private car? Possibly, but just have a careful check over for signs of excess wear and tear and if you're concerned, walk away; plenty more out there.

Hi Paul,

It could be down to a number of factors, but excessive fuel consumption can usually be traced to a few specific areas:

Are the tyre pressures correct all round? Tyres that are under pressure can seriously increase your fuel consumption.

Are you using a roof rack or roof box, or are you constantly carrying around heavy loads in the boot?

Has the engine been serviced recently?

Finally, there’s your own driving style, which is often the bigger contributing factor to fuel consumption. If you’re trying to save fuel, try accelerating a little more gently, anticipating the traffic flow a little further ahead, backing off earlier and not idling the engine when standing still for long periods.

Hi Jackie,

It should be pretty solid, although if it’s the 1.9 TDI diesel then they can suffer from fuel injection and air mass sensor issues. Also, with a car of that age, you’ll need to check everything (literally everything) to make sure it’s working OK. If it’s in good condition and comes with a full service history though, then it should be fine.
