Hi Gerard,

Check the air conditioning to make sure it's working - that seems to be a perennial A6 weak point. Also make sure that the engine has had a regular top up of oil - they do get through a bit between services. Check everything electrical too especially if any of the warning lights on the dash are on. ECUs (Engine Control Units) are also a bit fragile so take a long test drive with lots of hard acceleration and check for any drops in power.

Hope that all helps

Hi Sharon,

Short answer - yes, the clutch is one of the few major reliability weak points on the RAV4. The gearshift was always a bit heavy, so ignore that, but if the clutch feels wrong or is making any untoward noises, it needs replacing. Of course, an automatic version would get you around that issue, and there's no tax penalty for the extra emissions - both versions will cost you €750 a year to tax. Generally speaking it's best to get the lower mileage car, but the rule, as ever, is to buy on condition and history, not mileage. If the higher miles car has been better cared for, it's the better option.

Hi Auke,

We asked Mazda about this and the official response was: "Simple answer is it is not available in Ireland unfortunately. There are only 1,000 examples of the limited edition 25th anniversary in the world and we have one press model for marketing/PR purposes really - not for sale."

Sorry to be the bearer of bad news

Hi Marcus,

For 2006 and 2007 (and up to July 2008) the BMW 320d was taxed according to its engine size, which is 1,995cc. That is currently €710 per year (€394 for six months or €200 for three months).

If the car was registered after July 2008 then it is taxed according to its CO₂ emissions. Our data shows us that should mean emissions of 128g/km for a manual 320d or 144g/km with an automatic gearbox. The annual tax disc costs for those is €270 and €390 respectively.

Hope that helps

Hi John,

Yes, by and large Golfs are well enough built to withstand years of abuse, but then this is an older car so there are some areas to check...

Make sure the cambelt has been changed, check that the water pump is working (quick warm up from cold, but no issues with holding the temperature at idle), listen for noises from both the front suspension and steering, check that the air conditioning (if fitted) is working OK and make sure that the gearbox (manual or auto) is shifting cleanly.

Oh and avoid the FSI petrol model - they don't like regular 95RON unleaded petrol.

Hi Sean,

A nice car, and that price looks very sharp, but tread carefully. The 2002-onwards E-Class gave Mercedes-Benz and Mercedes owners no end of trouble, with anything electrical or electronic being exceptionally suspect. Now, the good news is that the 2006-on version of that E-Class was significantly revised and a whole lot better, but still check every single button and electrical connection to make sure it's all working properly. Make sure too that the gearbox and rear suspension are both working smoothly and not making any untoward noises - both are weak areas.

Hi Claire,

The revised Polo is now in Ireland, so we assume you mean that one. The 1.2-litre TSI petrol model is in Band A3, costing €190 to tax. That's the case whether it's manual or DSG automatic and for both three- and five-door body styles.

The only 1.4-litre Polo on the Volkswagen Ireland price list is the TDI diesel. It's available in 75- and 90hp guises, in both three- and five-door bodies and with a DSG automatic for the higher power unit. It doesn't matter which of all those you buy, they're all in Band A2, costing just €180 per year to tax.

Hope that helps, but please do check out our first drive of the revised Polo here as well.

Hi Lizzy,

Well, for a start, you're looking at two different segments here. The 3008 and Qashqai are much larger than the Juke, which is really quite a small car, especially on the inside. So, if you're regularly carrying large people or large loads, then I'd cross that one off your list. It's a little hard to say exactly how reliable any car is, but a good indicator is the result of the JD Power customer satisfaction survey. The most recent one, done in the UK last year, showed that Nissan was in the top ten for reliability and satisfaction while Peugeot finished in the bottom four.

Take from that what you will.
