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 Jonathan,

Land Rover's reliability has been improving out of all recognition lately, and the RR Sport is based on the third generation Discovery, which is a generally reliable vehicle, so that's good news. Watch for issues with the gearbox and anything that has an electric wire attached to the back of it. Check all buttons and switches work properly and that the car has a full and complete service history. Make sure the air suspension raises and lowers as it should too - leaking units can be expensive to rectify.

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 Ann,

I'd say between €2,500 and €3,000 if you're selling it yourself, or around €1,750 as a trade-in.

Hi Jeff,

Yup, really good. Nowhere near as slick or handsome as the current model, which was introduced in 2010, but exceptionally reliable, comfy, spacious and quite nice to drive. Just inspect any potential purchase carefully to see if it has been bounced around too much off-road.

Hi Ken,

If the shudder stops when you stop accelerating then we'd suggest looking at the inner CV joint.

Hi Niamh,

You shouldn't have a major problem as long as you look after the car and keep the service history up to scratch. Opels are perennially popular second hand buys, so while the badge means you won't get the value retention of, say a BMW or an Audi, there should always be a reasonably willing audience out there for one.

Hi Ash,

It very much depends on your price bracket and what your requirements are in terms of size. If you want something small, cheap and fun to drive, why not try either a Nissan Juke or MINI Countryman? Need something with a bit more space and practicality? Nissan Qashqai then, or better yet, a Skoda Yeti. Want to get something with a lot more size and some proper 4x4 ability? Go for a Honda CR-V, a Hyundai Santa Fe (you can get those with seven seats by the way) or, a Nissan again, this time the under-appreciated X-Trail. Want something seriously big and impressive? Well, a Range Rover Sport is always a good buy but be sure to put aside plenty to cover the running costs. A Toyota Land Cruiser is rather less exciting to drive or to look at but its reliability is little short of legendary. Or, if you want something really cheap and old that can pack some abuse and come back for more, try either a Suzuki Grand Vitara (smallish) or a Mitsubishi Pajero (big). Both are reliable, both can off-road properly and both can be tracked down at bargain prices, as long as you buy according to condition, not age or mileage.

Hi Matthew,

Wow, that's a brave decision. First off, the RX-8 is and always will be one of our favourite cars - light, agile, fun and with that screaming rotary engine up front. It's a gem of a car, and pretty reliable too.

Now the bad news. It's going to cost you a fortune to insure. You say you're starting to learn driving, but you don't specify your age. If you're under 25 you may well find it impossible to get any cover, but if you still live at home you may be able to do the old named-driver-on-your-parents-insurance trick. Even if you're over 25, as a first time driver your insurance is going to be well and truly loaded - the RX-8 is a proper sports car (and occasionally tricky in the wet) and most insurers will not be keen on insuring a novice on such a car.

Assuming though that you can sidestep those hurdles, go for it! If you start your driving career with an RX-8 you'll be getting off to a terrific start. One word of advice - invest in a high performance tuition course to help you better understand the ins and outs of driving a fast, rear-drive car. It'll make you a better driver anyway and it could save your life.
