A1 CARS J-Cars also known as A1 Cars RIP OFF CUSTOMERS Park Royal London!!. J-Cars sold a s car to us for over 5,000 pounds, and hid from us many faults with the car. The car was also sold as 2 owners, but had 4 owners. When tried to complain to J-Cars, they changed the name of the company from J-Cars to A Cars. Avoid this company at all costs.
