I have 18v vinal and black hood lining. I've just retrimed it as original and I don't notice it being hot as I thought it would be. Saturday it was 38 and i parked in a car park for 3 hours and it didn't bother me. I do think the tinted windows helped. I'm happy with the vinal, much better than my postie bike which after 10 minutes in the sun will fry your bum. Your choice Will but it is much better than I imaged it woul be.
