Best car buying company to use?

[stuart-ermrc]

Hi, I’ve been looking at prices for my car over various car buying companies. Over the past few months the prices being offered are only going up. I’ve found that there are 3 sites that are generally the most competitive but theres one I don’t know anything about. Has anyone on here used GoodByeCar before? They are giving me a decent bit more this morning for my Mini than the other sites but I don’t want to turn up only to be told the price is actually a few hundred pounds less than being offered. I’ve been honest with the condition of the car. Thanks
