If any of you have GAP insurance though i suggest you check the T&C's... there is usually something about modifications in there.
Excellent point! Chances are slim, but there's at least one owner here who wrote off their Mk5 not so long ago, so defo worth bearing in mind!
I wonder if claims' assessors go onto internet forums to investigate what owners do to their cars? Wouldn't be too hard, esp if that owner posted about the accident!
