If you want similar power then as you probably know it's the K04 Ed.30 you will be after. I doubt there will be much difference in build quality, perhaps a slight adv. to the Golf... the centre console is a nicer area in the Golf if I remember the Seat. Other than being a strange move... I'm sure you'll have all the same experiences with teh Golf as the Leon... same engine, brakes, exhast etc. I'm sure I will be corrected....
