UPDATE
i spoken to the guy up at the garage and he has fogged me off saying its a nice car, and said diddums because its not the 150bhp and its the 120bhp. and what was i expecting it to be a ferrari and he said im not having my money back. how rude is this guy.
so im now writing a letter for him, when they say reasonable time length how long shall i leave it to be classed as reasonable?
