Good point, I won't spoil your fun! Yeah get the basics checked like variator, cambelt change, rear suspension, windows, electric aerial, wipers (make sure the intermitant works) make sure you give it a thorough check over check the lights, electric door mirrors, air-con, radio everything!
Look for dodgy repair jobs, paint blending, overstrays etc and see it under sodium lighting if possible to check for any colour mismatch.
Finally go with your gut feeling. If you think somethings not right believe yourself and don't let your heart get in the way!
I had a red phase 2 spec lusso 2.0. Much nicer than the phase 1s so get one of these is possible. Even better get a spider, but the newer ones are much prettier.
