Hi Blaithin,

In my personal experience the most efficient car I've ever driven was the Volkswagen Golf BlueMotion - it easily averages better than 60mpg in everyday driving and I'm not the most economical of drivers. €20k should get you a nicely specced 2010 or 2011 model.

How does that sound?

Hi Audrey,

Go for the Tiguan and go for four-wheel drive if you can find a good one within your budget. That first generation Kuga didn't age well at all (interior feels very cheap and nasty now) and the last time I drove a four-wheel drive version I struggled to get better than 35mpg out of it. By contrast a 4Motion Tiguan should easily crack the 40mpg barrier in everyday driving, has a lovely cabin and is crackingly good to drive.

Hi Brian,

OK, at that budget you have plenty of good options. How about a Hyundai i10? Crackingly good little car that - nice to drive, safe, economical and really reliable. Circa €9,000 should get you into a 2012 model, and that will still have around three years of its original warranty left to run. Want something a little cheaper than that? Try a Suzuki Swift. Budget around €6,000 to €7,000 to get a 2009 or 2010 model. Again, a cracking little car to drive and Suzukis are exceptionally well made and reliable. Finally, if you max out your budget, you could get into a brand new Dacia Sandero 1.2. Not the most sophisticated car out there but simple and solid and it comes with a full warranty.

Hi Clo,

Nothing to worry about on the reliability front anyway - we've been trawling the web for Tuscon owners ranting about problems and there just don't seem to be any. The only concern is over the fuel economy, not that it's bad, but it does seem to be inconsistent and it's not helped by the fact that the Tuscon's trip computer is apparently calibrated for US gallons, which can make for inaccurate read-outs. There's also the fact that the Tuscon was designed and built when Hyundai was just on the cusp of its transformation from budget brand to major player, so things like cabin quality and refinement are merely OK, rather than the excellent ratings we tend to give the current Hyundai range.

Hope that helps

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 Mary,

First off, no you're not crazy. The Clubman is a terrific little car and I actually own one myself. It's more practical than you might think and much more distinctive and different than the standard MINI Hatch. Secondly, on the alloys - blistering could mean that the paint finish is peeling off or that the metal underneath is starting to corrode. It may be that you could simply sand down the bubbles and have the wheels resprayed, or you may need to budget for some replacement wheels.

The only major mechanical issue is a recurrent gearbox problem that can lead to failure and replacement. As long as it shifts gear cleanly, you should be OK. Don't worry if the shift feels heavy, as they are supposed to feel like that. 

Other problems are persistent interior rattles, issues with the stop-start system and a windscreen that seems to be peculiarly prone to cracks and chips. No issues with the timing belt as long as the service history is up to date.

Hi Brian,

Well, when you say 'super car' that would suggest that money is no object so...

Your choice is slightly limited as there aren't yet any full-on mid-engined diesel supercars, but there are three German powerhouses in the shape of the BMW 640d Gran Coupé, the Audi A7 3.0 TDI Bi-Turbo and the Porsche Panamera Diesel. (There's also the new Maserati Quattroporte diesel, but it pales in the power and torque race a bit.)

Of those the BMW is the best - frugal and well under the 225g/km limit but damn near as quick point to point as an M5. 

If budget is an issue, just grab yourself an E60 BMW 535d. Wheelspin in third gear in that one...

Hi Valerie,

If you're looking for something reliable for just doing short trips then get yourself a Toyota Yaris. I know, I know, not the most exciting car in the world, but reliable as the day is long and with a 1.0-litre engine (that's surprisingly peppy and powerful) your tax bills will be as affordable as possible.

Hi Au,

In terms of trade in, you're probably only looking at a value of around €1,500 or so. You might just break the €2,000 barrier if you try and sell it privately, but selling private is never easy. If you love your Leon  then can I simply suggest trading up to a newer one? If you go for a 2009-on second generation Leon, with the 1.6 TDI diesel engine, then you'll have a superbly economical car that will cost you only €200 a year to tax. You already know how robust and reliable SEATs are, so I don't need to remind you of that, but it's worth pointing out that the second-gen Leon was better to drive and more spacious than your current car. My dad has had three now and won't have anything else, so that recommendation is as good as it comes.

Mind you, it could be worth holding fire for a week. The Budget's coming up next week, and there's just a chance that the Society of the Irish Motor Industry's (SIMI) 'Swappage' plan, to give those trading in six-year-old-or-older cars €2,000 off the price of a new one could get approved, and if so then it may be worth trading up to an all-new Leon, which is simply one of the best cars out there. It's even, whisper it, a bit nicer than the Volkswagen Golf...

Here's the latest on the Swappage plan

Hi Paul,

Generally speaking not too much trouble although it's worth bearing in mind that the 2006-on S-Class comes from a time when Mercedes-Benz was still suffering from problems in the electrical department. It's those electrics that are the most fragile point of any S-Class, especially the complicated Comand  infotainment and satnav system. Make sure everything works and budget some extra for problems in the future.
