Well basically some of you may know i;ve changed my scirocco to a 320d Coupe! but now something else has happend.

Bmw salesman told me the car had 3 owners and i'd be the 4th, but on the logbook i received yesterday says 5!!!
I've spoke to the dealership and they said theyll brim my tank and give me a service but i dont think thats even close to what they should be compensating me in. (some of you may not aggree)
Now am i able to reject the car? as i have been mis-lead / mis-informed about a vehicle i have purchased?
The salesman has admitted he was wrong and i also told him on the day of purchase i do not wish to buy the car if it has 5 owners or im going to be the 5th...
PS. Looking to go back to a scirocco 2.0tsi dsg

Help is MUCH appreciated. (any advice)
