thers nowt that he'll do different to a normal car, a good tip is to replace a few visible stuff like brake pipes and wiper blades, clean wheels of brake dust and take car through car wash (make sure it dry tho for him) bulbs need to be checked and seat belts all fastened in place. it just detracts from smaller, borderline stuff.
every car i get has new brake lines, safety and the above reasons. but every car has had a warning for one of the indicators bieng off colour!!!
it seems they cant be arsed so they write that down. i mean what else would it be flashing at the corner of a car??
