I'm thinking of buying a Lexus IS 300 i found for 19,999 or should I just what and save up for a Acura TL?

I'm italian and in our state there are a lot of lexus IS300..I can say it's a stupend car...but it's so expensive for manutention! and in italy we can't buy it cause fuel it's so very very expensive!! (about 2$/lt)...but if you haven't problem for fuel...don't worry!! but If you haven't got a lot of money, don't buy that car...It's better you acura TL!...sorry for my bad english
