If you decide to sell I could be tempted with your exhaust system and rear bumper..I've got a black btcc with the remus system & quite fancy going for the cupra look....
As to value, like you I've done loads to mine & value is hard to access as you'll never get back what you've put in..
Personally I'd strip what you can for standard parts E.G wheels f/c climate ( exhaust&bumper to me ha ha )
& try selling...
If it was me I'd be looking at list and thinking what can I transfer to my new cupra. You still got the oem stuff?
Im don't want to strip it down for parts & I don't want to spend hours putting it back to OEM, plus I don't have any OEM parts lol.
I'm going to buy a Cupra and stage 2+ it then leave it as my missus will drive it more than me. But I know what your all saying & thanks for some of the positive comments lol.
I'm thinking an auction site + 6k starting price = see what happens..
