I'm in the same boat. My 2005 Limited Roadster has 22K miles and lives in the garage full-time. I've been debating about selling mine. I love the car and it's a blast to drive. It will be 10 years old in January and looks brand new. However, it's not good to let it sit and I'm not sure whether there will ever be a collectors market for non-SRT models in the future to really make it worth holding onto.
