Hi Gary,

Hang on — do we mean miles, as in actual miles, or kilometres? If it’s kilometres, it’s high for the age. If it’s miles, then its astronomical. Either way, mileage is not a good indication of what sort of state a car is in. Condition and history are what you should judge it on. As for the engine replacement, it’s certainly something to raise a lot of questions. Fair enough — engines do fail from time to time, and it can happen to any car, but it could indeed be an indication that the car has been used very hard, so check everything very carefully.

Hi Joe,

The current model? It’s a little too early to tell, as it usually takes several years before any major reliability issues come to light. So far, they seem to be solid, and for the most part they use tried and tested Opel engines and gearboxes, so as long as you buy one that’s got a full service history, we wouldn’t expect too many problems.

Hi Fuad,

Hellish in both respects. The RX-8 is a terrific car, and was always one of our favourites, but they do suck fuel pretty badly. If you’re able to keep it above 25mpg on average, you’ll be doing well. Insurance is pricey because, even though the engine has a swept capacity of just 1.3 litres, it’s still a 190-230hp rear-drive sports car, and no insurer is going to be fooled by the engine capacity in this case.

Hi Tom,

All Mondeo engines of that generation that would have been paired with the LX trim level used timing chains.

Hi Fergus,

You've not told us the type of engine in the car, but for your information only the 1.6-litre petrol and 1.9-litre TDI diesel units have timing belts. The change interval is 75,000 miles (just over 120,000km) so if the car you're looking at has one of those engines then it should have had a timing belt change by now.

Other than that insist on a full service history and regardless of what the dealer says it's worth getting a car history check on Cartell.ie, as it covers UK and Northern Ireland cars in full.

Hope that's of help.

Hi May,

In general these engines are very robust and don't use much oil. Of course if any engine isn't serviced then its reliability will suffer. The Almera's can have timing chain problems in that case. If you're getting high oil consumption then you really should bring to a mechanic to ascertain why.

Hope that helps

Hi Kevin,

The mk1 Ford Focus was offered with two different diesel engines over its lifespan: the direct injection TDDi and common rail TDCi. Both systems use glow plugs with reports suggesting that the more modern common-rail unit has marginally more issues particulairly relating to cold starts. 

We hope this answers your question. If you require any further information feel free to let us know.

Hi Sean,

Nice choice of cars to be thinking about. Before we look at the stats of the cars, the driving experience in the 3 Series vs. the Audi A4 is quite different - and will be the deciding point for many, so please do try to get a test drive in examples of both. That's the case whether you go for the older 3 Series Coupé or the newer saloon.

Personally, I prefer the way a 3 Series of this age drives in comparison to an A4. It's more 'dynamic' and engaging thanks to the rear-wheel drive layout. However, not everyone likes that and I've heard non-enthusiastic drivers call the feeling 'skittish'. There is no doubt that a front-engined, front-wheel drive car like the Audi A4 will find more traction on snow and ice than a rear-wheel drive BMW (assuming neither has winter tyres), but our climate is too mild for that to be a serious car-buying priority.

In terms of running costs, the early versions of the E90 BMW 320d saloon and Audi A4 2.0 TDI 140 are very close and, as you'll be buying a car registered before 2008 with that budget then tax will be the same, as it's based on the engine size. The E46 320Cd coupé is a little heavier on fuel, but not much.

The 320d saloon has the most powerful engine of these three, though there's not much in it really.

Both saloons are generally quite reliable, though we'd recommend getting full service histories and getting mileage checks with Cartell.ie as each car has its own known issues that crop up from time to time - like turbo issues on the BMW and burning oil in the Audi. The E46 coupé is also reliable, though it's built on older architecture so won't be as modern in general.

One final thing to bear in mind. While the S line Audi specification is highly tempting, it comes with firmer suspension, which may not be to everyone's taste. Test drive it before committing. Likewise an M Sport version of the BMW 320d, though you may not find many of those within budget.

Now, whether you should consider petrol instead of diesel is a whole other story. The decision really should come down to your average mileage. The diesel models will definitely be far more economical on a long run or commute, but not in town. Likewise, you can get lower capacity engines in the petrol cars bringing your annual tax bill down.

If you want to discuss the latter point in more detail come back to us and we'll go through options.

Hope this all helps

Hi Susanne,

We really like the Audi A1. Despite its smaller size it'll feel like a big step up in terms of quality etc. from your 2002 BMW 3 Series. A nearly new model will cost you very little in terms of servicing as well and there's a wide range of efficient petrol and diesel engines. Our favourite is the 1.2 TSI petrol, though if you cover a high average mileage (say greater than 15,000km a year) then it's worth looking for the 1.6 TDI diesel version instead.

If you'd like more detailed assistance to find one that suits your budget feel free to get back in touch.

Hi David,

The short version is, I’m afraid, you’re going to struggle. Small cars such as that don’t generally sell well with diesel engines, as the petrol variants are very economical already, and the diesel versions are much more expensive. We’ve found one on Carzone.ie (a 2005 VW Polo TDI),  but that was literally the only one we could find on sale that fits the bill. You might want to consider upgrading to a larger car — there are lots of diesel Golfs etc around in your price range.
