1994 Supra TT - Possible purchase would like some help ?

[The Miester]

I have been offered a Supra TT Aero Top in Silver, 88K Miles for £4,500. It is in execellent condition. Very fast. Failed MOT on headlights (which are currently Zenon) and rear brakes. I know the guy who is selling it very well, but he doesn't know enough about it to give me more details, because he he has too much money and wanted it for some fun. It is a import. Just looking for any advice, questions I should be asking, things I should look for ? Never bought a super car before ?
