I sold my car to chequers. Everyone I spoke to and encountered was very professional and kept me updated with payment process and car collection time (they gave me a very accurate one hour time frame so I could still plan the rest of my day).
A friendly gentleman came to where I lived to collect the car ( he had come all the way from surrey by train during the heat wave) and he made sure the payment had gone into my bank account before he left in the car.
I would definietly recommend anyone to sell their car to chequers.
