Well, Blue book suggested retail for 2002s is 33-35k for both of em. (not the z06, just the 'vette coupe). So teh price is identical for all purposes.
As for safety and convenience features (not necesarily quality) the vette has a tilt wheel while the bimmer has side airbags and optional sunroof. Thats it.
The vetter has 35 more HP, and 109 more lb/ft of tourque. Also makes it at 1800 less rpm. The vette has lower compression, and they get almost equal mileage with the vetter getting 1 more MPG in the city. negligable. Weight? basically identical. The vette is longer, wider and shorter.
The vetter has far more cargo room, but a 40ft turning circle (thats huge) as opposed to teh 34 feet on teh bimmer.

That being said, with teh expcetion of power, and even then, mainly just torque and the powercurve, they are identical in almost every regard. Its purely a matter of what feels better, and the image associated with each one. One may be of better build quality, but will cost more to fix when it does break. and all cars do break eventually. One may look cooler, but cost more to insure. Its all a matter of drivers opinion. Test drive em both and pick whichever one you find more enjoyable.
Personally, i dont think i could drive a 'vette yet. They are friggin huge cars. They may look big in picture, but in person that thing is massive. And the HUD in the vette rules
, though mainly pointless. Just whatever you do, dont even think of getting the red leather if you get a vette :shudders at the thought:
