Aye... I went from a Scoob to a Cupra TDi, which was okay for a while... but always missed the scoob... decided I would do a "grown ups car" and got a 4.2 V8 S6 Avant... but even with 300bhp and a V8 under the bonnet it had nothing on a scoob... traded it for the 06 STi. Both cars had the same same amount of power but were VASTLY different cars. No question, I wouldn't be without a scoob now, even if it was the cheapest "crappiest" oldest one I could afford.
Still got the Cupra TDi alongside the STi and it's a good combo IMO, Leon is cheap to tax, insure and run, STi... ummm... isn't, so between them we have the equivalent of two "normal" cars
Would definitely say if you've done that much to the car you'd be daft to let it go for FA (which is probably all you'd get for it atm).
