I just did about 2500 miles in about five days. My Z3 (2.3) held up pretty good. Even the seats (which I have bitterly complained about in the past) were pretty supportive. Aside from the noise, it is hard to believe that I completed the journey in a roadster. One thing that was different about the Florida Z3 scene was the number of fellow Z3ers that enthusiatically waved at me. One guy in New Smyrna (green) practically fell out of his car from waving so hard. No doubt, Florida is good roadster country.
