I have owned a couple 911's and now own a Jaguar F Type R. Wanting to add a Cayman S and wondered if there are years or main issues to steer clear of? I have a 2007 S manual local in the color and miles I am good with but unsure how dependable and solid the S model is in this year. I saw something about scored pistons in the S models and go for the base model. Any insight is appreciated.
