I bought my car from Mercedes Direct. They sell thousands of demonstrators, courtesy cars, and short term lease cars. Think about it, they have 000s of cars to sell, how many demonstrators does one manufacturer need. Surely the whole idea of these vehicles is a means of the manufacturer discounting its cars without reducing the sticker price.
I saved about £9,000 by buying my car from MB direct rather than the main dealers. Although it is true MB direct piles em high and sells them cheap. My whole family went out on test drives in Classic, Elegance and Advantgarde spec cars tosee what we preferred.
My car comes with a fantastic warranty, a 30 day exchange plan, MBs own warranty, the car comes serviced,/repaired and is indistinguishable from the showroom car. I'll not be going to a main dealer again as my car is great!
