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 Adrian,

There's no doubt that premium cars of this age can come with costly repair bills. The older they get the more likely something will go wrong, no matter how reliable they are in general. The example you're looking at already has quite high mileage so we'd say budget for a grand or so of repairs a year just in case.

This generation of the A4 was reliable enough. Most problems seem to have stemmed from heating and cooling systems (in particular the air conditioning) and electrics so thoroughly inspect the car - preferably with a bit of professional help. Ensure that the gearbox (assuming it's manual) is smooth and noise-free and that there is no clonking from the front suspension.

Hope that helps

Hi Val,

Generally it's a bad idea to fit mis-matching tyres across the same axle of a car (i.e. both front tyres should be the same and both rear tyres should be the same, but front and rear can be different brands etc. so long as the size is within manufacturer guidelines). In an ideal world all four tyres would be matching, but we realise that people need to save money.

On that note, we'd urge caution with regards to buying second-hand tyres. You can't possibly know their history and though they might be fine, it's still not a great idea.

Final point from us: a tyre is one of the most important parts of your car to maintain safety. Please don't scrimp on that.

Hope that's been of assistance.

Hi Catherine,

That's an interesting one and the decision will probably come down to your personal preference. The Discovery certainly has a higher 'status' and it is a very good car, but a newer, highly specified Galaxy might be the logical choice. Both cars are relatively reliable and highly comfortable. The Galaxy has more space and probably more equipment, but that depends on the Discovery you're looking at.

One thing to be aware of is that the Discovery is likely to have higher running costs, from fuel, tyres, servicing and insurance to annual road tax.

Bear all that in mind and then take the Discovery for a good long test drive before you decide - and don't be tempted by 'too good to be true' prices either. Get a Cartell.ie history check to make sure there's nothing dodgy about the car you're considering.

Hi Brian,

Good timing! We have the GT86 on test this week. Here it is on the very twisty and very bumpy Dublin Mountain roads:

Review will be done in time, but I can confirm that it's even more impressive here than it was at the launch in Spain. Its small size and low weight are ideally suited to tight and twisty roads and though firm, the suspension deals with rough surfaces and bumps (even mid-corner) brilliantly. The none-too low profile tyres no doubt help with that.

On the open road it's hugely engaging and very fast. It feels weightless and while it goes where you point it there's a lot of movement underneath if you want it. Turn off traction control and it regularly slides too - though don't expect big drifts on the public road!

While it is lacking a little in low-down torque, it's only an issue for overtaking, as the car feels quick at all times, and is very quick if you use all the revs.

Away from driving for the fun of it, the GT86 is still brilliant. Some might not get it, and it's not quiet, but it even works well in town, where its small size, quick steering and relatively supple suspension mean it doesn't feel at all out of place.

Overall: a fabulous car. Really works on Irish roads. Really special.

Hi Dermot,

This doesn't appear to be very good value to us. Even though your Passat is probably only worth €1,000 or so to the dealer, the mileage of the Santa Fe is above average and the price is therefore quite optimistic - though clearly the service, tyres and NCT make it considerable more appealing.

Hope that helps

Hi Simon,

That is a lovely car, but you need to be prepared for the high running costs. Annual road tax alone is €1,683, while it's also heavy on fuel. No doubt it has low profile tyres as well, which are expensive to replace.

It seems to have very low mileage for the year, so make sure you get that verified. If it's right then it's still fairly fresh, but this generation of the 3 Series is expensive to maintain once the miles rack up.

Go into the deal with your eyes open and it could still be a great car for you.

Hi Keith,

Yes you can is the simple answer. However, for the speedometer to remain accurate you'll need to ensure that the overall diameter of the combined tyre and wheel remains the same. That means a 14-inch wheel will need a deeper profile tyre than you had on your 15-inch rim.

If you need more explanation come back to us and we'll talk you through it.

Hi Patrick,

It does indeed have full-time four-wheel drive. It's called xDrive and in normal use the power is split 68:32 rear to front but this can be varied to as much as 100% rear-wheel drive.

Larger cars like SUVs are always a little harder on tyres, but the X3 is not unusual in that regards. It has a good reputation for reliability with no known suspension problems.

Hope that helps.

Hi Patrick,

On its own, the RAV4 2.0 D-4D is a fine car, with loads of power. It has plenty of low-down torque for towing too, though how heavy is your caravan? The manual Santa Fe has a higher towing capacity and it's a heavier car too, which will help in certain situations. Added to that, the Hyundai has more power and torque - (assuming you're talking about the newer 2.2-litre model) though obviously you pay for that with fuel consumption and tax.

Both cars have a good reputation for reliability though in fact it's the Toyota that has some history of issues - particularly with RAV4s used as tow cars. Apparently early versions (pre-2003) had transmission problems, though we'd hope the 2005 model is better.

Still, based on what you've said, we reckon the Santa Fe is the better bet in this instance, especially the newer model launched in 2006.
