i just bought a manual 300 tdi,
in the main for work use, which covers towing
machinery and green refuse, and consecutive motorway runs, it returns a graet MPG(last check averaging Above 30, motorway runs def. coming into play here), Power and ease with towing is brilliant, total confidence in it.
Have a nose about on other threads and see all round Auto performances to help in your decision, and ensure whatever you buy is giving you optimum performance relative to condition.
