i have one......and i fokin love it.
things ied look out for.....
look past the nice clean engine bay and look in around the battery cradle making sure the looms and the leads to the plugs are ok.
listen for noisey pulleys
look in the engine bay for wires earthed to the chassis for the likes of after market accessories , make sure the earthed propperly and the looms are heat shrunk.
do your best to check the exhaust, mine had a weld right where the backbox meets the centre section so the option of fitting a back box only was out so i fitted a cat back.
when you take if tor a test drive make sure its warmed up of it will feel sluggish......on my car the temp goes up to half way and sits there when warm, also idles at 1500 rpm when cold and settles down to around 500 rpm when warmed up.
thats all i can think of for now.
