Good choice Gaz! What you got - the 899 or sporting?
Look for the same things as a Cinq - they are essentially the same car. Handbrakes seize up, head gaskets can go, shockers and rear wishbone bushes too and the obvious bits - look for any signs of crash damage.The main things to look out for and avoid are noisy tappets on the 899cc (loud ticking noises from the top of the engine), blown head gaskets on both the 899 and 1108cc Sportings, cam belt changes on the 1108, crash damage, and a service history is always nice.
It's really rather important that you get the red key with the car, (unless you've got the post 2000 one, this uses a different system with no red / blue keys). This is the master key for the immobiliser and should be kept in a safe place, and the 2 blue ones should be used for day to day use. If you lose the blue keys and don't have the red one, it's big bucks to fix.
Service it yourself to keep costs down, or use somewhere like National to do oil changes for you (they can do you Hypergrade and a filter for less than you can buy the bits yourself...)
Mainly it's just plugs, air and fuel filters, and cambelts for the routine stuff. Be aware that 1108's are supposed to have the valve clearances checked every 36k miles, and they are adjusted by changing shims - this isn't really a job for a novice.
Then drop a Punto engine in it
