Well, some dealers have realised this is a fantastic marketing opportunity ...
Have run AUDI's for many years now & every time I've been into the dealership for servicing been given something different ranging from 2 AUDI A6 estates; 1 TT convertable; 1 A4 convertable and a A4 Quattro... max 6 months old, loaded with just about every conceavable extra you could imagine (well Huntingdon & Maidstone AUDI do this)
Excellent opportunity to 'try before you buy', was specifically why I got another & was easily suckered into an extra 4k's worth of options... sales guys already knew they didn't have to sell.
