20K into a scoob plus say 10K on a base scoob and your looking at 30K.
Agree about 911's and unless its a GT2,3 or a turbo they are just girls cars.
But Horses for courses and everyone has a different requirement, but at 30k I would much sooner have a new shape E92 M3 saloon.
Or leave the scoob alone and keep it as is, and get a 2nd toy car for 20K. Caterham etc.
