Seriously tho lol, whos done it ? someone must have !
My sister's first mini had a sunroof (I just went for a convertible mini) hehe..... But her sunroof was fitted by Rover and supposedly the best job you could get at the time, it was fitted before she bought the car.....
It was rubbish! Basically, if you're prepared to have wet seats every winter where the condensation drips off the glass onto your interior, then fine, but otherwise, I wouldn't bother! You really don't gain that much having a standard sunroof- come to think of it, I've had two 'modern' cars with leccy ones and hardly ever opened them!
A webasto full length roof is very cool... My sister-in-law has a late Cooper sport 5 with one, the only thing you have to watch with those is the actual roof fabric shrinking over time in the sun and curling round the edges!
Oh an I just remembered, our mini van Momo, also has a sunroof, fitted by the previous numpty who owned her (What div would do that to a van?) if we could have taken it out we would, but it was far too much work... The only problems we get with that are drips when you go round bends after it's rained.....
