I'm looking to get a A3 2.0TDi Sport from the main dealer (2nd hand). It is a 2003 Model (03 Plate), Akoya silver and no optional extras apart from the usual Sport wheels etc. The car has 20K miles on the clock and I will be doing roughly 30K miles a year. I'm looking at buying this over 4 years but wonder how much it will be worth when I look to sell it (4 years time) with approximately 140K miles on the clock? How hard would it be to sell it given the high miles? Is 140K classed as high miles as most Diesels I guess would be purchased to do lots of miles so would this be the norm? Cheers Rich.
