Mine went on Friday night, no warning. Took the roof off and the motor was flooded ! Soaked it in WD40 dried it in the sun along with the foam and put it all back together. Apart from a few broken clips no cost, but what a job to do on your own.
Took me about 6 hours to get it all out and about 5 hours to clean everything and reassemble. Spent a lot of time removing the interior trim, roll bar plastic etc. The clips and 7 bolts holding the "hoop" were a challenge both to remove and refit. Few aches and pains, getting in and out of the boot is a challenge for someone my size and age !
Great satisfaction getting it to work again and saving a fortune, our dealer charges close to £100/hour so I'm sure I've saved over £1,000.
Really hope I don't have to do it again though.
