There are no major issues to look out for.
The fuel is quite a big hit, bare in mind you're going to want to put Branded fuel in, rather than untreated super market stuff.
I average about 110-120 miles on £20 of Texaco Standard and about 100 miles on £20 of Texaco super.
Servicing is expensive when going to main dealers, if you buying second hand and its over 3 years old, get it done privately.
Parts aren't a worry, they generally don't go wrong, if they do, generally about the same price as any other car.
Beleive me, I'm skint every month after paying out on the loan and insurance, but when you drive down the road and watch the heads turn you will grin from ear to ear!
Await the perfect strangers telling you how nice your car is !
You won't look back ! - You may a week before pay day tho!
The performance is ok, I'm only 20 so there's not a lot I can get thats any quicker, but I won't be happy until i've got 300 horses under the bonnet.
Don't bother with the S model if you can afford better, go for a sport, tints and polished stuff etc.
Get a black one!
