No way would i pay £1500 for a one year warrenty!
Especially with a £250 excess anyway, id be wanting a no excess policy for that amount of money for sure!
Anyway, i thought these cars were meant to be bullet proof once theyve had the bottom end recall done (earlier ones), and the rear bushes and springs done? And as said, whats going to cost you £1750 (£1500 + £250) to get done anyway? The other common problems, the bushes and springs wont cost anywhere near the price of the warrenty either.
Anyway mate, in answer to your question, no it wouldnt bother me in the slightest. Its a good way of trying to get some money knocked off though.
