Tom,Yes, I have owned my 2003 smart passion coupe since March 2006, one of the first 85 cars that were converted by G&K for the US market. We have loved every minute of owning it. There are approximately 1000 of the 2002-2006 smart cars in the US at this time.
The new 2008 model coming out in January from smartusa.com will be 8" longer and has a larger engine (non-turbo though). Many enthusiasts love the old model because it is still the original body style inside and out, plus has the Mercedes engine instead of the Mitsubishi engine.
