V8 Car

Buyer a car on finance with V8 Luton- stay away from them- alternator belt faulty and squeaking at the point of sale and the guy just said its because it's sat in the garage for a long time and went ahead and sprayed with b40. I have changed alternator and belt myself as it was faulty as discovered at local garage in March cost 500 just 3 months in. I had to change 2 front tyres from point of sale as they were completely worn out. Now 9 months later automatic gearbox box completely broken. Finance company advised to get engineer to look at it and establish fault timeline and in report said point of sale/ only driven 3000 miles myself. Now since September they have not acknowledged the finance company request for contact in any way...as many of you said they sell faulty cars - now I'm stuck financially/ without a car and completely heart broken
