I remember taking a Cayman S out when they weren't that old. Parked the Zed up all clean. Took the Cayman for a blast. The grip was unbelievable (that was the sales dude driving though I NEVER push cars that much!) but apart from that, very underwhelmed. Sure the interior was nicer but it just wasn't worth the £45k price tag. The whole time I was in it I was thinking, slightly older C4S..... I love 911s so it would have to be a 911 for me.
My mate (independent German specialist including Porsche) put me off with costs if things go wrong! He did say get an older one, much better.
Although going to GT3s and Turbos is a different thing altogether!
I can't wait to see the pics.
