Get the 3.2
It is by far a superior car - its even better than the 8P S3 (braces for the impending abuse)
comming from an 8L S3 it would rape the A3 3.2 anytime any day it is lighter concerning that acceleration isnt bad... besides a 3.2 v6 to tune is a nightmare.. better off getting 8L s3 or an a3 2.0TQ
must remember the newer ones are heavier and bigger to the 8L my 8P feel like a limo for godsake lol
as for repairs turbo's dont cost that much these days in England
