Here is an example of an early Fiberglass 308 which seems to be a good bargain:
Coys Fine Motor Cars
An Important Auction of British and Continental Sports & Touring Cars, Motorcycles and Collectors Items
Thursday 3rd March 2005
1977 Ferrari 308 GTB
Registration no: TAP 720R
Chassis no: 22399
This early 1977 308 GTB was purchased by it's New York based owner in 1996 from its first owner a Californian collector who was forced to part with the car in a divorce settlement. At the time of purchase the car had covered a mere 18,000 miles and current mileage stands at 23,000 miles. TAP 720R was imported into the UK in 1998. More recently it has been carefully dry stored and benefited from a full service prior to this which included 4 new tyres, a new distributor and HT leads. Reluctantly for sale only due to a lack of recent use, the car comes with valid MOT certificate, is on the button and is ready to be enjoyed by its next lucky owner.
