We have a 10 year old TT which sits under a metal carport when not in use. It gets cleaned inside and out after every outing. Never had a leak or othe major issues. People have commented on how "new" it looks.
The point - if the TT has been cared for then I would not worry about buying an older TT. If the unit had a leak, then it would be obvious by now (stains on the walls - inside and out).
See if the dealer will offer a "non-leak" guarantee for say 6 months - to put your mind at ease. All mechanicals are pretty simple and if your handy then you should be able to rectify any issue.
But it is 8 years old - so don't expect it to be perfect but also it should not be trashed.
