Iso Grifo GL
The Iso Grifo was designed by Giorgetto Giugiaro at Bertone and featured a sophisticated chassis by Giotto Bizzarrini. Initially powered by Chevrolet Corvette V8 engines, later models used Ford 351 Cleveland V8s. The combination of lightweight Italian coachwork (around 3,000 lbs) and 300-400+ horsepower American engines created a genuine supercar that could embarrass Ferraris costing twice as much. The GL variant featured quad headlights and improved aerodynamics. Only about 400 Grifos were produced in total, making them exceedingly rare today. Build quality was exceptional, with hand-formed aluminum body panels over a tubular steel frame.
Verify authenticity with Iso register as replicas exist. Check chassis thoroughly for rust and accident damage. Ensure engine and transmission are correct for the year - most used Chevy 327, 327L, or 427, later Ford 351. Examine aluminum bodywork for cracks and previous repairs. Test all electrical systems including pop-up headlights if equipped. Look for complete documentation and service history. Budget significantly for maintenance as specialist knowledge is required. Consider joining the Iso & Bizzarrini Owners Club. Expect six-figure values for good examples.
