End Value

Have managed to pick up a GTI cabriolet(white with black roof) with 132.900 miles on it.
It has been off the road since 2009. I am looking at restoring this vehicle including a full
respray. How would I be able to get a rough idea of what it would be worth if it was
restored to a decent standard?

Honestly unless its a special edition of some kind by the time you've spent money on a respray (depending on the standard) then you arent going to have any worthwhile profit in the car.

Despite the prices you see on ebay its realistically only a 5k car

Agree with 1985, difficult to restore MK1s and make money unless mega rare like Yomps early S1 press car and if you count his time spent then not so much…

Only worth doing as a hobby or if car is a family heirloom.

If you do restore it to a high standard you know its done right and then enjoy for many years.

Think the restoration profit potential is at the wendyball end of the classic market, Aston Martins, Ferraris etc
