Many thanks for all the considered opinions. It looks like the Boxster is the generally preferred car, although this gives me a good excuse to go out and have some fun driving a variety of samples (I think my local Carmax has a Boxster and S2000 in stock at the moment).
Any thoughts as to which of these cars (Z3, Z4, Boxster, S2000, MB, etc) is closest to the bottom as far as depreciation is concerned. I don't expect any of these cars to remain steady in value year to year, although i would like to consider depreciation in the decision process.
