YEP!! It's 100% legal. I drive 88 seriesIII with the top off as much as possible in the summer. Get a cover for it mate,you can't get that top on and off that easy by yourself if you want to leave it off for long during thte summer.The rain is a bitch.I also found that the more I left it off in public,the more it become a mobile rubbish tip for passers by.Not a pleasant suprise at 6 am. Anyway....yes it is legal as long as you have and are using your seat belt,never had any probs with the fuzz.
