Hi Hawk,
I'm in Western PA, near Pittsburgh. I put a reservation in 9/16/08 for a white Passion with silver trim, panoramic roof, and comfort pkg. Price, MPG, ESP, and safety ratings were what motivated me.
I have the same question that you do regarding the high mileage. I consistently put about 500 miles per week on my Santa Fe. Driving that much, it's easy to have over 100k miles in 3-4 years.
I did google searches for "Smart wieviel km" and "Smart quanti km", and saw one person had 150,000 km on his last Smart and another said their aunt had 200,000 km on her Smart, but these were just quick searches... I would like to hear more on the high mileage topic too.
