This C4 is in perfect showroom condition, never seen rain and was stored in a climate controlled garage for 32 years here in Arizona up till last March when I bought it from a dealer on eBay who was selling it for the family of the deceased original owner who was a North Scottsdale home builder. I have replaced the the fuel filter, fuel pump and the the mass air fuel sensor with a NOS Bosch unit same as the factory unit. This vette runs perfect but I have found that when the outside temperature is over 90 the motor runs too hot at stop lights even with the extra Z51 fan. I talked with Bill Martens Chevrolet' Special Programs manager and he said he would try going with 2 electric fans but it may need a new 3-4 row radiator to run in traffic over 90 degrees.Robert623-584-8020.
