They are reasonably durable. There are pressure points in the rear that can cause stress cracks if you crawl up there. I've seen people in parades put two young women up there and wondered if they had some spiders above the deck lid when they were done. They are not any more suspectable than several other sports cars I've owned. By the way, why would anyone sit on a speedster. Now, sex on the front fender is ok. Not on the doors, you'll be readjusting them; and I'd avoid high points on the rear altogher. Also, regarding sex, keep you weight off of it and choose a reasonably sized partner.
