Hi Tim,
Any pics or link to the car and/or details?
Apart from the Cambelt/water pump and the other usual bits (as mentioned) that should be done if the car has been on a time and distance service plan I would pay attention to the Edition30 specific item. Some cars when nicked and stripped have parts replaced with normal (lesser) parts. Have a good look through some interior pics of other cars for sale on Pistoheads/eBay and Autotrader, I would print some of those pictures off to check against. I've seen an Eddy in the paspast with a standard mk5 steering wheel, standard GTI gears knob, non OEM Headunit and as mentioned check the wheels.
Let us know how you get on.
Cheers
