BCA dont even comply with their own rules.
Here's my gripe, 5 years ago I purchased a Renault Megane (I know your going to say that its my fault, but hear me out) It stated warranted mileage of 62k. I sold the car and 3 months later after a few issues which I had sorted out for the customer, it turned out he was like a dog with a bone he started to question the miles and managed to find out that the history was forged and the mileage was incorrect, it had actually done just over 135k, They had done a great job of hiding it. This didn't go down well with any of us as you can imagine and when I approached BCA explaining the mileage was warranted, they told me that whatever the vendor states, is their liability. Well, they weren't very helpful at all, after several phone calls, they explained that the vendor is a regular seller and they had never had issues with them before, but conveniently the vendor went bankrupt and BCA didn't want to know anymore, they completely washed their hands of it, leaving me with an empty wallet, a very sour taste in my mouth and a very upset customer.
If warranted miles doesn't mean that the mileage is warranted. WTF does anything they say mean?
I haven't bought a car from BCA since, and my reputation is back in tact.
