Disappointed C

Terrible dealership

After being promised a great deal on a new car I ordered one as a replacement for my old one. 2 days before collection after waiting 6 months for the car the dealer rang me to say they Now wouldn’t offer me the same second hand value for my car as it’s 6 months older and has more mileage on it. They told me it would cost more than £140 more than what I was originally quoted. So I cancelled the new car. They are now not paying my deposit back of over 10k. Avoid this garage like the plague
