hi all, i recently sold my 2003 audi a4 1.9tdi sport, fully kitted, why i dont know, but a guy wanted it and paid me what i paid neearly a year ago, i kind of regret selling it, but it did have a few we niggley faults in paint work on bodykit, that kind of annoyed me, plus i wasnt keen on the look of it,(colour wise) but it was otherwise a good all round car, i wanted to remap it but sold it before i got the chance,anyway i have considered a bmw 2002/3 330d sport but hard to find clean low mileage at good price, then i have recently came acros a 2002 a4 2.5tdi qauttro sport, kitted with 19,s, 65k, F,A,S,H... which is local, i have never drivin the quattro, but am considering this as an option, could anyone please shed any knowledge on these for me, i like economy in my car, was only getting 450miles/tank on the 1.9...my mates was closer to 550?? is the 180bhp quattro slower or feel slower, less economical, any faults with the quattro system? is the front suspension set-up the same? i have had 2 a4 tdi,s before, 1 a sport and the other se, i think he said the belt has been changed, bit premature i would have thought at 60k, but its done anyway, car has all the extras, armrest etc etc....

what should i look out for? cheers, also what is the CO,2 emissions on these, tax bracket? i cant help but watch my average consumption while i cruise!!
