Hi Anthony,

It depends on the year of your current A6, but while there's not a huge jump in emissions by going for the V6 TDI, there is a big jump in price so it's certainly not going to be cheap. Others well worth considering are the incoming new BMW 5 Series with the 530d engine (or consider arguing yourself a good deal on a runout current shape model), the excellent new-shape Mercedes-Benz E 350 d or the Jaguar XF 3.0 V6 D. Test drives below to tease you further...

Hi Michael,

I’d suggest that a Passat GTE or 330e would be about perfect with that kind of mileage and usage. It will help, of course, if you have a driveway where you can fit a charging point, but once the batteries have drained and you’re running on normal hybrid power, both of those cars will average better than 40mpg.

Hi Des,

It depends on just how big a car you need, and if you need a full seven-seater. The Volkswagen Golf SV, for instance, has the space for three seats across the back, but doesn't have the folding seats in the boot of the bigger Touran. Both are excellent cars, but you'll save a considerable amount of money by going for the SV. Others worth considering are the Toyota Verso (available in both five- and seven-seat forms), Citroen C4 Picasso (ditto) and the Kia Carens (only a seven-seater).

Peugeot's 5008 and Ford's C-Max are also worth a look, but if you need something bigger, if basically boils down to two choices - Ford S-Max or SEAT Alhambra.

Hi Patrick,

Classic cars are, currently, an exceptionally good investment, but I would exercise a touch of caution – back in the eighties, the same was true and values seemed to quadruple every week, but then came a massive crash in classic prices, which saw more than a few investors get their fingers (and in some cases hands, wrists and elbows) burned.

There are a few specific models and makes to focus on, but first off don’t assume that you can buy an old wreck, restore it and make a profit. Sometimes you can, but proper restorations cost enormous amounts of time and money and many restored cars are actually sold at a loss.

There are some cars that are pretty safe bets though (albeit that comes with the caveat that values can fall as well as rise). The best car for investments seems to be the Mercedes-Benz SL, of pretty much any generation. Mid-sixties ‘Pagoda Roof’ SLs are probably at the peak of their values now, but the later ‘Bobby Ewing’ models still have some viable investment room. The better bet, though, could be to get in on the ground floor of the R129 SL model, built from 1989 to 2002. They’re still relatively affordable, and if the values of their predecessors are anything to go buy, you could be looking at a serious rise in values in the next few years.

Obviously almost any Ferrari is a viable investment tool, although you will need to seek out specialist advice on that one, and it’s getting harder to find affordable ones that have a chance of a good rise in value. Porsches, especially early-model 911s, are a good bet too, with original RS and RSR versions being a solid investment.

Beyond that, anything rare, interesting or, better still, with a celebrity name on the logbook, is worth a look, but as with all investments I’d engage the services of a professional financial advisor before committing to anything.

Hi John,

No, it’s not just another cost to the consumer. Stop-start systems are designed to prevent the car from running the engine unnecessarily at standstill when doing so would be at its most wasteful of fuel. After all, if you’re not moving then what is the point in having the engine on? Stop-start systems are specially designed with either a beefed-up alternator or an integrated starter/generator so that it can handle multiple stops and restarts in rapid succession, and it’s estimated that on an average car, stop-start can save as much as ten per cent of overall fuel consumption – not to be sniffed at, never mind the benefits to city-centre air quality.

Admittedly, the car makers have brought in stop-start to bring their cars' official CO₂ and fuel consumption figures down, and the benefits are only really felt if you are stopping and starting regularly. If you spend all your driving time on the motorway then you won't use the system at all.

Hi Philip,

You’ve pretty much summed it up there. I guess it depends where your priorities lie – performance or comfort. There’s no doubting the sheer thrust of the 300hp Audi, but I would suggest that if it’s performance you crave, skip the Cabriolet and buy the Saloon, which is much better to drive. If it’s the open top that you fancy, then go for the Mercedes, forget about performance (although the Merc is hardly a slouch in that regard) and instead revel in the comfort.

Hi Pat,

Here’s our review of the new Toyota Prius.

And as you’ve mentioned Toyota, you could do worse than start with a current Auris or Avensis if you’re looking for something with a comfortable ride on Irish roads. Other good options are the Citroen C4 Picasso or, if you fancy something a little more premium, a Mercedes-Benz E-Class.

Hi Harry,

RRP is the Recommended Retail Price and it’s the price at which the car maker and importer thinks the car should be sold at, in basic form minus such things as options or delivery charges. It’s possible that the car you were looking at was being quoted as net of any extra equipment and the delivery charge.

Hi Jim,

Nothing to avoid, in particular, but lots of good ones to try out. Start with a Mazda6 Tourer, or a Ford Mondeo Estate, or a Skoda Superb Combi. If you want to save a bit of money (but not compromise on space) go for a Skoda Octavia Combi, if you want something with a bit of class go for an Audi A6 Avant (pricey but the 2.0-litre TDI keeps running costs down).

Hi Deirdre,

Prices for a 2007 Mondeo seem to hover at around the €5,000 mark, so as a trade-in you’re only likely to get offered €3,500 or so – dealers have to allow for some profit margin and expense when it comes to valuing cars.

If you’re going to sell privately, I'd pitch the price at around the €4,500 mark and see how you go.
