I purchased a car from BCA which had a mechanical report. This shows the car has a good battery, drives well but has a bit of smoke from the exhaust. The vehicle is stated as all good, with the exception of this "minor" problem. I have paid for the car, and got the keys, only to find the car does NOT start, is MAJORLY smoking both inside and outside of the car, and also is not capable of a drive home, and requires towing. They have my money and it is over £6k, which gives them the upper hand. I have NOT removed the vehicle as it is not as described and they are threatening to charge me £17+vat per day for storage. What are my rights? Surely the vehicle is NOT as described and I am entitled to a refund?
