I've had my '13 Roadster for 15 months now and still love it. Everywhere I go, especially with the top down, I get raves from onlookers. Just a fun car to drive!!! However, I don't think it's suitable for a "only" vehicle. Just too small for hauling extras around unless a person rents a bigger vehicle for those few times more space is needed.
I had an '05 convertible and wanted to replace it with a '13 S. When I stopped in at my dealer, I saw the Roadster and quickly forgot about getting the convertible. No regrets.
