I just realised this is the 'boat' section.
So your mk3 probably weighs 25% more than a mk2
"who ate all the pies?, who ate all the pies . . . . .?"
Slight problem with what you're saying. According to evo magazine (the bible as far as performance cars are concerned), a 1988-1992 Golf GTi 16v Mk2 weighs in at 1111Kg. A Mk3 16v weighs in at 1181kg - a gain of 70 kilos, which is nowhere near the 25% you were quoting.
Looking at the numbers actually, there was twice as big a weight jump from Mk1 to Mk2 as there was from Mk2 to Mk3. I wonder if the people who insist on calling the Mk3 a boat realise this - the Golf actually went on its biggest pie-eating binge when the Mk2 came out.
