Neither my wife or I like the styling on the Vette.
Another roadster we gave serious consideration was the Pontiac Solstice - but after reading reviews the cute styling just wasnt enough to get us hooked.
Another one we considered briefly was the Lotus Elise, but I fear it is too small for me, and I am not sure we want to deal with owning an imported car. Just smells like it is a little too much trouble.
Would like to see more suggestions though - we are far from actually putting money down so more choices would be interesting
The 60k for the Z4 M is probably the upper limit of what we want to spend.
