too many variables m8 1) location cars are cheaper farther south u are = supply and demand 2) SERVICE HISTORY plays a big part new recent timing belt tensioner plus w pump can be had for £300 but may make the difference of £500 or £600 plus or minus on selling price , body work condition is generally marked as average good or very good as per Glasses guide ? 3) standard versus non standard , personally id only ever buy a standard vehicle and mod it myself ( by standard i mean engine wise ) cosmetics are a plus, I looked at several 1.8t sport qs and and several s3s before purchase, in particular I found the 1-8t qs of this vintage all had serious problems ,........ lowered , turbo problems , re-mapped etc etc having spent 20 years in the motor trade id say you have 3 options depending on the above and the condition of your car cheap 1) = £1800 - 2k = modded remapped pile o shize, 2) standard model needing body work or 4 new boots and has some service history 2k -2.5k , pristine example new tyres full service history needing absolutely nothing £3500 , just be honest with yourself m8 what u ask for and what u need .................
