Hi SRGTD, thanks for your comment, I appreciate it.
I understand what you are saying and been told the same thing by friends at work. For my budget and the spec that I want, the GTI will probably have over 100k miles as opposed to 50k+ on a diesel. I currently own an Audi A4 (B6 model) that I bought with 86k 12 years ago. Now has nearly 174k and still runs well.
Basically, I am looking for:-
2014-2017,
No more than 2 previous owners,
White / Grey / Black (in that order),
50k to 80k miles,
DSG transmission,
Decent service history,
Optional buying points would include:-
Leather interior,
Santiago wheels,
Dynaudio.
Thanks.
