I know there's a specialized workshop for mini coopers at the mass car workshop after Summit hotel.
go to the summit, then turn left at the big junction, always fuking jam there. den at the next trafic light, turn right. while u at the trafic junction u can see giant infront, further up is the new mydin. after u turn right, u juz go straight pass a trafic light, den turn left 1st junction. texchem factory n office on ur right. infront is chop shop n lots of workshops for cars. u look for a shop with a lot of fuking mini parked outside...
