Hi Karen,

If it's the 1.6 petrol you should be fine - it's the diesel engine that gives trouble on older BMWs. Have a good poke around it all the same and make sure it's been looked after properly. Make certain it has a full service history, and check for obvious signs of abuse like parking scrapes or battered alloy wheels.

Hi Philip,

Not all marques and not all models use AdBlue as yet. AdBlue is a urea solution that can be injected into he exhausts of diesel cars to neutralise a significant proportion of their emissions of nitrogen oxides (NOx) - very much in the news at the moment of course. The rule of thumb is generally only that larger, more powerful engines need an AdBlue treatment system as many smaller engines don't need the assistance. Each manufacturer, and indeed each individual engine, will have its recommended AdBlue top-up times, and it will be directly related both to mileage and how much acceleration the car has been doing. You can top up the AdBlue tank yourself - a 1.5-litre refill should cost around €11-12.

Hi Anthony,

Don't worry - cracking car. Not quite as nice as the current-model i10 but still reliable, solid, nice to drive and should do you for a good while. Just make sure it's been serviced properly (preferably with a Hyundai dealer).

Hi Selvamani,

Not really. Lots of good cars, and good deals, out there. If you've got money in your pocket (as opposed to needing finance) then the world is your oyster. Obviously you need to choose one that won't lose its value too quickly.

Hi Breda,

The golden rule is never buy on year or mileage but on condition and history. As you say, both cars are in immaculate condition but I'll bet that one or the other has a better and more complete service history, and that's the one to go for.

Hi Charles,

I assume you mean this Volkswagen story. At this stage we have been told that it only affects certain cars powered by the 2.0-litre TDI engine, but not all of them. So, going by current information, the 2014 model year 1.6 TDI Audi A3 Saloon is not effected. Keep an eye on our news page and social media feeds however, as we expect more news to emerge in the coming days.

Kind regards

Hi Joan,

It's a bit of a quandary to be honest. You'll get more for the Ibiza - probably around €7-8k as a trade in. But with the Toledo costing you money, your best bet might just be to keep the Ibiza and use that as your small car, chop the Toledo in for whatever you can get for it (€2k max and that's with a following wind).

Actually, better yet, why not avail of one of the scrappage schemes still being offered by some car makers? Opel, for instance, has a good one going - up to €4,500 - and you could then trade in your Toledo against a new Insignia; far more affordable than a BMW or Audi, and with a shiny new warranty to boot. Reliable and nice to drive too. Nissan also has a similar offer (potentially €4k against a nice new Qashqai perhaps?), or potentially €3k scrappage off a Hyundai ix35?

Lots of good options out there.

Hi Lorraine,

It depends on the condition and history. If one has a full service history, has obviously been cared for and is in great condition - and the other isn't - go for the one in better nick. That overrides any question about diesel versus petrol. 

However, assuming the two cars are in similar condition and both have decent histories, petrol versus diesel comes down to mileage. If you're doing more than 15,000- to 20,000km per year, then you need to be thinking about diesel. Below that threshold petrol is the better option, unless of course that low mileage is all at high speed on the motorway.

Hope that helps

Hi John,

The critical question here is how much road tax and insurance pain are you willing to take? An early 2000s Porsche 911 will crack 5.3 seconds 0-100km/h all day long but you'll pay through the nose for tax, disc and servicing. And never, ever buy one without a full Porsche or Porsche Specialist service history.

Most Mercedes-AMG models from the same era will do similar but again the same caveats on servicing and running costs apply.

A BMW M3 Evolution will do 5.5 seconds, but watch for ones that have been badly fiddled with or modified.

Probably better would be a Ford Focus RS or a Volkswagen Golf R or R32. Both are pretty rugged in the reliability stakes but again you have to be wary of cars that have been modified or altered from standard. 

However, possibly the best bet is a Honda S2000. As long as you don't need back seats it's a fantastic thing to drive, will do 6.0 seconds 0-100km/h and it's rock solid in reliability terms. Loads around well within your price band but again watch carefully for badly done modifications or cars that haven't been cared for.

Hi Enda,

I'd tread carefully here. If you don't like the semi-auto box on the Citroen then just let it go - it's not going to get any better and it'll bug you for the rest of your time with the car. 

As for the Renault, I'm just not confident predicting reliability. Generally, Renaults are now a lot better built than they used to be, but long-term they can still be a bit shaky. Also, the reason it's a high-spec 2010 model for such a small price is because Renaults depreciate faster than snow in summer. 

So, I think you might need to shop around a bit and buy something on the basis of reliability and condition rather than year. Have a look at the likes of a Ford S-Max, Toyota Verso, Volkswagen Touran or, if six seats rather than seven will do the trick, a Honda FR-V. You might need to go back to a 2008 or 2009 model to get one within budget, but buy with a full service history and keep the maintenance up and any of those should give you long and hopefully reliable service.

Last, but not least, Shane, our Editor, is in the same position as you right now and he has homed in on the Mazda5, which has an exceptional reliability record.
