Honestly, just ask The simpsons boys.
They are hardly going to ruin their reputation by selling a shit car. Besides they know their stuff, and the guys on here that regularly use them are guys I would class as "the lads". They are not daft and use them because they are good and honest.
We would only sell a car out of our garage that we went through with a fine tooth comb, its not worth the hassle otherwise
As Shimmy says, if you are not entirely happy, dont buy it just because it might be the cheapest CSL out there.
Im sure it will be fine though.
