Why keep somebody from buying it? If I were that worried about my z getting wrecked I wouldnt sell it anyway. Ive seen alot of older people that try to drive right and still dont know how? I started on z cars when I was 16 and havent really abused one yet. Just my opinion though. But i wouldnt let it go for any less than 16 or more. I hope you know what you are doing and dont regret getting rid of it.
