Hi George,

By and large, if you’ve got a Volkswagen on a list, then it’s going to be the most reliable, and the Caddy is hugely spacious inside too. However, most vans are generally very reliable (simply because a van that’s off the road isn’t earning money), so as long as you’re buying carefully and with a full and complete service history, you should be fine with any of those listed.

Hi Seamus,

The rule of thumb is never buy on mere mileage, always buy on condition and history. If the car has a full service history, that's a good sign. If the garage is willing to stand over it with a warranty, that's good too, although it would be worth pushing to see if you can get a full year. Don't forget also that the 'mileage' is actually 'kilometreage' and that 100,000 is actually only 62,000 in old money.

For what it's worth, our own 2009 MINI Clubman has more than 100,000km on the clock and it still looks and feels like a new car (when I remember to clean it). Mondeos are built to a pretty high standard, and as I say, once that service book is fully stamped up and the dealer seems reputable, then you should be fine. At least you can be confident it's not been clocked...

Hi Paula,

Yup, you're onto a winner there. A lot of motoring writers get a bit sniffy about the Nissan Micra, but actually it's a car with which there is very little wrong. That third generation model that you're talking about is actually probably the best one of all, with a nice, comfy, spacious interior, a peppy little 1.2-litre engine and a chassis that's actually more entertaining to drive than you would think. Of course, the automatic gearbox will sap a little bit of power, but as long as you're not entering any traffic light Grands Prix, you'll be fine. Reliability simply shouldn't be an issue as the Micra has always been conspicuously well built. Just check carefully to make sure it's been serviced regularly and that the oil for the automatic gearbox has been changed regularly too.

Hi Seamus,

A Mondeo 2.0 TDCi is, frankly, a great choice - spacious, comfy, well made and superb for that kind of long-haul journey. Just as a suggestion though, it may be worth coming down a class and having a look around, just as a way of potentially keeping your running costs as low as possible. Perhaps a Honda Civic diesel or a Skoda Octavia TDI? Both are massively spacious (so would carry your height with plenty of space behind for baby seats etc.), but would also be a little cheaper to run than the Mondeo, and almost as comfy on the long haul. Worth a thought, but if you fancy the Mondeo, go for it. Buy one with a full service history and you won't go wrong.

Hi Noel,

We can’t tell you if a particular car is worth buying or not, but we do like our Jags and the 2003 onwards XJ was a very nice one. Common problems include broken door handles, leaking boot seals, a rattling from the engine caused by faulty tappets, broken ABS sensors, knocking suspension meaning the dampers are shot, leaking dampers, failed air suspension pumps and basically anything electrical.

While the XJ was always well made and reliable, you’ve got to remember that they’re hugely complex cars and need to be cared for properly to remain reliable. If there are any gaps in the service history, or the car seems tired or worn out, then walk away.

Hi William,

In general, Renault has picked its reliability game up over recent years,  but we would still advise a little caution. Electrical problems are quite common, especially with the windows and the engine management system, so buy carefully and make sure that it comes with a full service history.

Hi Bill, glad we're of assistance - spread the word!

In answer to your question, it's something of a yes and no. Yes, you could potentially find a cheaper 5 Series by shopping somewhere other than a franchised BMW dealer, but why then try and buy a warranty from BMW? Part of BMW's second hand car warranty package is a full inspection of the vehicle and a check of all major components. Assuming that they would warranty your car unseen, there would almost certainly be a loading on the premium to reflect the fact that they are effectively insuring an unknown car against failure.

So, I would suggest one of two things - either stick with the full franchised BMW second hand package (which is actually pretty keenly priced once you factor everything in) or buy elsewhere and go to a third party for the warranty insurance. Mapfre is pretty much the only game in town in Ireland for aftermarket warranties at the moment, and it has a simple online application form so you can work out the cost of the warranty before you buy the car. Here's the company's website.

Hi Gerry,

As ever, predicting a second hand value is a tricky thing, but I'd say start between €5-6k for a trade in, and see how you get on.

Hi Stella,

OK, the good news is that your Yaris is an in-demand model and values for cars from around that era are holding up well because of the scarcity of new car sales since the financial crash. I'd hope that you'd get around €8,000 for it, but let's play safe and assume you get €7,000 and you can add your €1k to that. That opens up an entire world of MINIs to you, and not just old models - you should be able to get into the second-generation post-2006 model, which is noticeably more refined and well made. I'd suggest trying to track down a nicely specced 1.6 Cooper and enjoy the heck out of it. As a MINI owner myself, I can tell you that they're great fun to drive and not quite as impractical as you might think.

Now, reliability. There's no two ways about it - Toyotas are staggeringly reliable and break very rarely. MINIs aren't bad, not bad at all, but they're just not quite as bank-vault solid as the Japanese car. Buy carefully, make sure you get one with a full and complete service history and you should be fine. Regular servicing isn't too pricey (about €190 for a normal service) and fuel economy should be pretty good too.

Hope that all helps

Hi Mervyn,

Generally speaking, most car makers design major parts such as engine heads, blocks etc. for a life of around 400,000 to 500,000km. That said, if you look after the car properly, keep it serviced and be prepared to spend the cash to replace major components from time to time, the total life is essentially unlimited. It’s all down to the care the car gets a lot of the time.
