Hi Ian,

If nothing else, you need to adhere to manufacturer servicing schedules to ensure you don't invalidate your warranty. If you don't trust your local dealer then contact Opel directly, though these figures should be in your owner manual as well.

Besides all of that, we'd thoroughly recommend servicing modern diesel cars regularly, as the car makers often push the service intervals out to appeal to fleet buyers. Regular oil changes in particular are a very good idea.

Hope that helps

Hi Joan,

Yes, absolutely worth considering. Yes, the mileage is a touch high, but Mondeos are built tough so as long as it's been serviced properly, there shouldn't be any major issues.

Hi Myles,

With that length of a daily commute, I'd reckon that you should definitely go for diesel and back in 2008 there was actually a choice of Focus diesels, with the run-out 1.8 TDCi and the incoming 1.6 TDCi both available. Both are excellent choices, with the 1.8 possibly having an edge on overall reliability (it's an older and more proven design) but the 1.6 having the edge in terms of fuel economy and emissions. Find a well-cared for example with full service history (those diesel injection systems are complex and need looking after) and you won't go wrong.

Hi Tony,

OK, there are a couple of issues here. One is that a trawl of the Internet forums, especially in the UK, seems to indicate that there is a common problem on the N47 2.0-litre diesel engine whereby the timing chain can either fail or jump its sprockets. Either way, you're looking at an engine failure and a need for replacement. Not a trivial matter. 

However, BMW has not issued a recall or any specific advice in this area, which may indicate that there has not been a significant level of these incidents. It's easy to accuse a car company of ignoring a major problem but actually that's rarer than you'd think and it's all to easy to get into a froth of indignation from just reading complaints on the internet.

That being the case, we'd simply advise caution. There are some very good independent BMW specialists out there (such as http://www.bloomfieldgarage.ie/) and it might be worth getting in touch with them for more detailed advice.

Also, insist on full service history with these cars, paying particular attention to oil change intervals.

Hi Helen,

The general rule of thumb for trade in values is to look at the forecourt price for an equivalent car and subtract around €1,000 to allow for the dealer's costs and profit margins. 

As for a valeting service, it would depend on where in the country you live, but a quick run through the good old Yellow Pages should turn up several in your area.

Hi Carmel,

You haven’t given us a year, which makes valuing a bit vague, but assuming it’s a 2012 X-Trail, then the value is in the region of €10-12,000 - depending on condition and history.

Hi Erin,

Well, I have to put my hand up and declare an interest. I own a MINI , a Clubman Cooper D, and it's fab. Fun to drive, funky to look at and super-economical (it averages better than 55mpg). So I'd say if you're interested in a MINI, go for it. 

Just make sure anything you're looking at buying has a full service history. Don't forget that these are small BMWs with plenty of complex bits and need to be cared for accordingly. It's worth looking at MINI's 'cherished' second hand programme, from franchised dealers, which a gets you a two-year warranty and a full check over.

Hi Dawn,

Yes, getting it checked by Cartell.ie should flag up whether there is anything dodgy in the car's history. Have a look through the service book too and maybe have a ring around the various garages where the car has been looked after.  If the car was regularly serviced and/or they know the owners, that should be a good sign. 

If you're still concerned, get the AA to inspect it for you. They go through second hand cars with a fine tooth comb and will flag up any potential issues.

Hi Heino,

Check for vibration from the dual-mass flywheel on the 2.0-litre engines, and that the drain at the bottom of the windscreen has not become clogged with road debris and leaves. If it’s the 2.0-litre TDI and it’s smoking a lot, then the turbo is probably gone or about to go, and that engine needs a cam belt change at 120,000km.

Check the rear brake discs for excessive wear or scoring marks too — the electronic handbrake can stick on and damage the disc. Check everything electrical carefully in general for a car of that age, and don’t buy without a full and complete service history.

Hi Stephen,

Depends on the history really. If it's got a fully stamped service book, is in good nick and a background check on its ownership gives the all clear, then it might just be a genuine bargain. If a history check reveals any skeletons (outstanding finance or that it was stolen or written off) or if there are huge gaps in the service history, or indeed if the seller seems shifty or evasive, then you know the old saying about things that look too good to be true, right?

A good start is a history and finance check with www.Cartell.ie
