The Mk2 Cabrio would be in fact an Mk3 and because it's a cabrio there's no way it's lighter than the ST. Additionally the ST's traction might not be one of it's best features but a Golf Cabrio's is WORSE ! ha ha! Early Golf GTI's are legendary for their performance that's true, and it's mainly due to the low weight, but Golf Cabrios (and that includes all of them) are legendary for their poor handling. I worked for 7 years in a VW dealership and drove many different Cab Golfs (new, second hand, etc) they were all crappy!
