I am very interested, if your Z is still for sale. A few questions: 1. Is this an automatic or manual tranny? - 4 or 5 speed? 2. Did you resolve the radiator problem? IS it a 3 or 4 core and what is the fan set-up - clutch-driven or electric fan and how many fans does it have. 3. Do you think that an A/C system can be installed? (I live in Phoenix) 4. What else does the car need to be reliable? 5. AZ has emissions test requirements - can this car pass a standing emissions test? Thanks. jfrankel@medaire.com
