When I bought my kit a couple of years ago I also bought the donor & a pair of Cobra seats,thinking that's the main expence done with. Well it's taken 2 years before seats were installed in the car & shown off to guests at our Easter BBQ. "Your seats don't match" was the main comment; & on closer inspection we could see they didn't,not a great difference but once pointed out, the error glared at you every time you entered the workshop. We wrote to Cobra explaining the mis-match & they replied"Difference due to change in prodution methods & we got seats from before & after. Please return the seats & we will send back a matching pair" Seats returned last Monday & replacement MATCHING seats recieved on Friday. What brilliant service 2 years after purchase, full marks & a highly recommended company.
