I ran my RCZ through it and it did worse than the Z4
... guess thats two cars I'll be scrapping then! The only way this will benefit you is if you get a high score that you can waft about to a potential buyer who hasn't got a clue. A lot of the cars on this forum are owned by people that fix squeaks and rattles immediately, (some cars on here are in better condition at 15 years than the average car at 3 years). I think in the 8 years I've owned mine it's been in the rain about 5 times. The previous owner of my RCZ wasn't a car person, used the MOT to gauge if anything needed to be done and then fixed it, the car is far from being a wreck. I've spent the last 5 months getting back to showroom condition, reports like this could/will only damage a potential sale.
