Personally I'd LPG the A4 if its your daily driver. The A4, whilst numb compared to the 156, i believe is a generation ahead - remember the 156 without the facelift bumper was out when the first A4 was on the road, and whilst I love mine, its not got the quality build of the newer 02+ A4 but compared to my dads '99 A4 Id have the ***** any day.
Differenc eI guess, no-one wil lcare youre in an A4, compared to the talking piece of the 156.. I get comments all the time about how nice it looks.. guarantee no-one outside a vw fan club would eye up the A4! (sorry)
