IMS definitely NOT fixed, but still just a 5-10% risk of it going. Bore scoring on the S much more troublesome, so always get them inspected regardless. As long as it’s fine, and again remembering that more mileage is better, buy and enjoy the finest sports coupe of the time.
The IMS was only sorted on the 2009 Cayman S that did away with it entirely and moved to the DFi engines.
