Hi David,

Oh yes. In fact, I couldn't recommend it highly enough. Smooth, powerful, terrific to drive and yet decently economical too. Aside from a touch too much road noise, the Octavia RS TDI is one of the most accomplished all-round performance cars we've ever driven.

Hi Jason,

Perhaps predictably, the DS5 has been a slow seller for Citroen, primarily because as soon as you put the words 'French' and 'premium' into the same sentence, most buyers tend to look for the exit. We are very, very wedded to our German premium cars in this country. 

The DS5 isn't a bad car at all, but to be honest, neither is it a very good one. It looks absolutely stunning, inside and out and as a piece of automotive sculpture, it's hard to beat. It comes with some excellent diesel engines too and generally its build quality and reliability seems to be up with the best.

The problem comes when you actually drive it and realise that it has steel girders for suspension. It rides terribly, clonking and clattering over bumps in a way that should be utterly alien to any French luxury car. A BMW 5 Series on 20-inch wheels rides better than this... Then there's the problem that the cabin is actually quite cramped, even in the front. It's a car we want to love, but there are just too many fundamental issues with it for us to do so.

Hi Emer,

Both are excellent in terms of reliability (they are after all a Mazda and a Toyota), but it's the Mazda that will be more fuel efficient. Simple physics really; while there's not much difference in the overall weight, the RAV4, being an SUV, is taller and therefore less aerodynamic. Unless you need (and I mean REALLY need) the RAV's extra ground clearance and rough road abilities, then a Mazda6 (especially the estate one) should prove a reliable, spacious and enjoyable ownership prospect.

Hi Alanna,

I reckon the Qashqai +2 might be the best one to go for. The extra seats are pretty small but the boot on the +2 is simply massive when they're folded flat, so that's helpful when you're lugging around two small ones and their various chattels. Don't worry about running costs too much - the Qashqai looks like an SUV but it's really a hatchback with attitude and the 1.5 diesel engine is reliable, economical and has reasonably low emissions too.

That Toyota 1.4 diesel you mentioned would indeed be much less powerful than your Mazda's engine - it's about 20hp down and noticeably so. Volkswagen Jettas are indeed reliable, but I reckon that the Nissan would be slightly more so, so make that your first choice.

Hi Tanya,

Actually, both cars have exactly the same engine - BMW's long-serving 3.0-litre straight-six diesel. The first generation X5 is little short of excellent, with terrific handling and a gorgeous, comfortable cabin. Reliability isn't the best though. The engines have occasional problems with fuel injectors and developing cracks in the inlet manifold, while steering and suspension are also prone to damage and wear. X5s are also notorious for chewing through tyres at a ferocious rate. The engine's air mass sensor can also fail, leading to poor acceleration although you'll spot that easily enough on a test drive.

Basically, it's worth getting any potential purchase checked over by the AA for any faults, and just ignore anything that doesn't come with a full service history. Oh, and it's better to go for the 2004 one - that should have the newer six-speed automatic gearbox (ignore manuals - they'll be worth much less come trade-in time) that improves fuel economy to just over 30mpg.

Hi Tanya,

OK, prices for a 2007 Kia Sorento range from as little as €6,000 for a commercial model to as much as €15,000, which seems a bit hopeful to me. Let's play reasonably safe and suggest that you should get about €9,000 to €10,000 on trade-in. 

Now, the 5 Series. The E60 5 Series that ran from 2002 to 2010 is one of our all time favourite cars and the 535d is one of the very best. Powerful, smooth, reasonably economical and able to spin the rear wheels in third gear. Ahem.

It's worth considering other models though. The 535d is a twin-turbo version of the same 3.0-litre six-cylinder engine that you'll find, in single turbo form, in the 530d. You won't save any money in terms of tax (it's the same capacity), but the 530d will be better on fuel and cheaper to insure. If you really want to save some money, look for the ever-popular 520d, which is almost ridiculously cheap to run and far more powerful than you might expect. 

As for things to look for, the suspension is the 5's weak point so if there are any nasty clonking noises or if the car feels unstable on the road, or the steering feels inaccurate, walk away. The iDrive infotainment system has also been known to give bother so check and make sure that it is working and, as with any prestige car, make sure it has a full service history.

With a car like this, I'd never advise buying privately or from an unfranchised dealer. SIMI membership should be at least the bottom line and you'll get a better deal from a BMW main dealer than you might expect, especially if the car is part of their approved used programme. 

A 2005 530d or 535d seems to hover around a similar asking price to your Kia so you'll just have to negotiate carefully to get the best price.

Hi Lisa,

Too utterly different cars but, thankfully, both ultra-reliable so both are good ownership prospects. 

So, it just comes down to what you want and what you need. The Honda is a little more practical, and will be cheaper overall to run. The Hyundai is bigger and more expensive, but also a bit cooler in its SUV style. Worth pointing out that the third row seats in the Hyundai are quite small, so if you're carrying a full load of people regularly it may be best to go for the six-seat Honda.

Hi Michael,

Well, it kind of depends on the car. If you mean something along the lines of a Hyundai i10 or even a Peugeot 208 (ok, so that one's a 1.2 but still...) then the answer is not much. Fuel economy should work out at around 50mpg depending on how you drive; emissions should be under 120g/km; and insurance should be dirt cheap.

If you're talking about an older model, the waters are a bit muddier. Smaller engines generally mean lower running costs but there are cars out there with underpowered smaller engines, and you have to spend so much time ragging them to keep up with the flow of traffic that your fuel consumption goes through the roof.

Hi Pam,

It's pretty close to brilliant as a second hand purchase - there are no major reliability or warranty issues to report on the FR-V. The only things to really look for are obvious signs of damage or abuse on the inside (they are used as family transport, after all) and the outside (they're wider than most cars so check for bashed panels or kerbed wheels). That 1.8 won't be the most economical engine ever, but it probably won't break the bank as long as you're not doing lots of long motorway miles.

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.
