reference the registration of your car, I would not worry about this too much, but I would not be pressured into accepting the car within 10 days. If they are going to rectify the problems within the 10 days, then no bother.
Regarding what seems to be the common suggestion to accept the car and try and sort it out later, I wouldn't! If your not happy they fix it before you accept it in my eyes. The warranty is something different all together.
Most of the faults you described in the previous thread sound as if they have been caused by the dealers poor preperation of the car.
Just because other people have 2nd rate quality standards, doesnt mean you need too.
£10k is alot of money in my eyes, and I am sure 99.9% of people would agree
