I wouldn’t trust any of their branches full stop.
Although tbh any dealer you buy from will give a certain amount of risk. It’s all about doing your homework on the car, checking everything is right before you make the deal and even more so upon collection, then contacting them immediately if you spot a problem. When spending £10K on something I wouldn’t have an issue driving to Scotland, if it was the right car. £100 in fuel is nothing at that point
