Apart from bikes, they make a lot of money selling 'tat' like lexus lights sunstrips, stereos, and cheap alloys, and obviously in a recession people's lack of disposable income, mean that they will no longer buy the 'tat', as they can no longer justify it any more (...how they before is anyone's guess)...
If they organised their 'parts desk' and trained the staff to be more helpful, and teach them another word other than 'no', they'd proberly do more business, as lets face it what other motor factors is open Sunday when you are stuck for something....
