Hi Karl,

Short answer? Track down a nice Golf 1.9 TDI. As long as you keep it serviced that old 'Pump Düse' engine is solid, 50mpg is easily done and it's comfy and sweet to drive.

What do you think?

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 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.

Expert answer

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 there,

I’d be slightly careful. Remapping can unleash more power and torque, but you need to be very careful that the chip comes from a reputable source and that it won’t unduly affect the reliability and fuel consumption of the engine. I’d have a word with the guys at the Volkswagen and Audi owners club of Ireland, VAGE, as they tend to know their onions and would be able to give you more precise advice.

Hi Penny,

I'm assuming you mean the second-generation Octavia, introduced that year? If so, they're a pretty solid car but one that needs a few checks. If it's the 1.4 petrol, have the cam belt inspected. They need doing every 60,000 miles anyway, but the 1.4 has a history of belt failures so it's important to make sure that the one on the car is sound. Check the cabin for rattles or loose trim, check the boot floor for damp carpets (the rear screen wash bottle can leak) and if it's a diesel check for any juddering or poor acceleration, which can be a sign that the dual-mass flywheel is giving trouble. Also, check again for damp carpets in the main cabin, which can be a sign that the door seals are leaking.

Hi Gillian,

Yes, it's really good. I've always liked the idea of a six-seat MPV with two rows (I'm also a Fiat Multipla fan) and the FR-V is just excellent. They're really reliable, spacious (even if that front centre seat is a touch cramped) and really quite nice to drive. Nothing major goes wrong with any regularity but just check the cabin for signs of family abuse beyond the call of duty. One downside - there's no compact diesel option, just the 2.2-litre diesel unit. That means you're much more likely to end up with the 1.8 petrol.

Hi Sean,

Watch for dodgy turbos, flaky electronics and issues with the brakes not being strong enough (more of a problem on the heavier V10 TDI to be honest). That 2.5 TDI engine does give pretty decent economy for a big 4x4 though, and it feels more wieldy and manoeuvrable than rivals such as the Land Rover Discovery or Toyota Land Cruiser.

Expert answer

Hi Tom,

That one came with the first generation of Land Rover's own V8 diesel engine (the Range Rover had exclusively used BMW's 3.0-litre straight-six diesel prior to that) and brought with it much more power and torque and better fuel economy too. Good points are the comfort, the style, the on-road deportment, the off-road capability (mountain goats glare jealously at you) and the image. Bad points are fragile gearboxes and electronics and the mammoth running costs - you CANNOT run a Range Rover on the cheap, even if you can buy them quite cheaply now.
