I have had my 182 cup for 6 months now. Just check all the electrics work, play with all the buttons!!! (including cruise control, etc)
Then take it for a test drive for at least 30 mins. Test the clutch after, mine was really sticky/ grindy!
On 19k miles you shouldnt have any problems really. Check the exhaust mounts and heat shield as these have a tendancy to rattle. Ummm think thats it.
You may also have problems with the front suspension struts. They creak when turning the car on full lock in most 182s.
OH and if you pay £5, you become a full member with access to the guides section!
This has loads of info on common faults and specs, etc.
