Hi Mark,

The more recent versions of the Renault Grand Scenic are at least reasonably reliable, and the commonly-seen 1.5-litre diesel engine is a sold enough old lump, and well proven in various Nissans and Renaults. The recurring nightmare is that of electrical problems. Renaults, older ones at any rate, just seem to eat through their cabling and wiring and everything from electric windows to engine management and injection problems can crop up. Buy very, very carefully if you're looking at  anything older than 2008.

Hi John,

You know what? Just avoid the lot of them. In the early 2000s Renault was going through a period of very poor build quality that wasn't really resolved until the launch of the current Mégane in 2008. Older Renaults are generally just to be avoided. Electrical problems are commonplace and frustrating, and just because they're working now doesn't mean they'll stay working. These cars are marked down in price for a reason.

Hope we were in time to stop you buying!

Hi Kellie.

Generally speaking, they should be OK. All the mechanical bits are old, proven Renault and Nissan parts, and thanks to the fact that Logans are pretty well shorn of equipment, there's not that much that can go wrong. Dacias also come with an optional five-year warranty, which should put your mind at rest.

However, it's worth pointing out that the Logan estate we tested recently had a wonky driver's door, putting some doubt over the quality of the assembly and the German TUV (the national safety and quality testing organisation) rates the Logan as having a 13 per cent fault rate. Now, that figure is only a guideline and it does encompass the old Logan (the one that was never sold here) as well, but just for comparisons, the TUV rates a Ford Fiesta at a 4.8 per cent fault rate.

In other words, they're probably fine, but try and make sure you buy one with lots of warranty left, just in case.

Hi Mary,

I presume that's either a Laguna or a Scenic you're talking about? In that case, it looks like a very good price for a car with very low mileage. However, with that kind of small miles on a diesel you need to be careful of two things. 1 - make sure that the previous owners have been doing enough long, high-speed runs to generate temperature in the exhaust system to clear out the Diesel Particulate Filter (DPF) and, 2 - carefully check the history of the car to make sure that the mileage is genuine. Renault build quality is generally a little better than you might think, but you still need to be more careful than with other brands. Check carefully that all the electrics are working properly, especially the windows, and make sure the car has a full and complete service history.

Hi Suzanne,

I'd be wary. That second generation Mégane doesn't have the best reputation for reliability. Everything electronic, the credit-card style ignition keys and the brakes can all give trouble, as can the window seals (water gets in occasionally) and the electric windows themselves. A total of 112,000 miles isn't the massive mileage it once was, but on a car with a poor reliability background, I'd say it's of concern.

Hi Chris,

We checked with Renault on this and here's the response we got:

"There is nothing technical to stop a customer carrying out an LPG conversion on the TCe 90 engine, but there is no manufacturer support to do it.  There is no such thing as 'an approved convertor'  for LPG on any Renault/Dacia so the customer would need to be satisfied themselves in the quality of work and warranty provided by whoever carries out the conversion.

"Additionally, carrying out a conversion does not necessarily invalidate the manufacturer warranty as a whole and is still valid for non LPG related parts. However, if an incident arises that is directly or indirectly found to have been caused by the conversion, that would not be our responsibility. In other words, normal warranty applies on anything that is not in any way connected to the conversion (e.g. an internal electrical defect with an alternator would not have been influenced by the conversion)."

Hope that helps

Hi Jane,

Sounds like you want to move back into a proper MPV and the best one around at the moment, for my money, is the Citroen C4 Picasso. Citroen registered a bundle of them last year for press and promotional purposes so there should be plenty of good nearly-new or dealer demo stock knocking around. It's a classy looking thing, comfy to drive and utterly massive on the inside. Other good options are the Ford C-Max (great to drive but the boot is slightly on the small side) and the Toyota Verso (a touch unexciting but with terrific quality and lots of space). Or, of you want something with a warranty to match the Mitsubishi's, track down a nice 2013 Kia Carens - a classy looking car with bundles of space.

Hi Rowland,

OK, there are a lot of parameters to go with here, but the basics are that you need a car that's cheap to buy (so it can't, sadly be too new), has affordable running costs and won't break down every time it rains. I reckon that gives you a choice of three or four key models: Honda Civic, Toyota Corolla or Auris, Kia cee'd or Hyundai i30.

Have a shop around and you should be able to find several of those all well within your purchase price range, while they all have efficient engines and excellent reliability records. In the case of the Kia and the Hyundai, they also have lengthy warranties, which, even if there's none left on the one you buy, at least means that they're more likely to have been looked after. My personal choice would be the Honda. Track down a nice 1.4 petrol Civic and I don't think you'll look back.

Hi Richard,

The Alhambra would be my choice here. A budget of €6,000 won't get you the current model, but it should find you an old one and they're still good. SEAT's reliability is pretty solid and you should be able to find one at a lower mileage than an equivalently priced (and mechanically identical) Ford Galaxy. 

It would be worth keeping an eye out for a Ford S-Max too, though €6,000 is the very, very bottom end for S-Max prices, but keep your eyes peeled and haggle hard and you might just land a nice one. 

And, as I always advise anyone looking for a seven-seater, there's always the option of a Mercedes-Benz E-Class Estate with extra seats in the boot...

Hi Bobby,

Well, it's a lot better than the old Mégane, but then that's not saying much... It should be fine, actually. That 1.5 dCi diesel is a solid engine, and Nissan uses it too so it can't be bad, right? Keep an eye on all electrical systems though as these seem to be a perennial Renault weak point and carefully check the rather cheap-feeling cabin for signs of excess wear and tear.
