clearly the answer is a used 2006
, after that a used 2004 (lockers) and then 2003 (locker,s). Then 1997.5/98. The TT4 vs. non-TT4 debate could be waged on either side. I for one have a 2001 and short of trucks with lockers have little to complain about.
In the end the biggest part of answering the question is what's the budget.
