About

1973 CHEVROLET VEGA GT HATCHBACK COUPE
Silver Metallic - Black interior

140 CID (2.3 L) Aluminum Block Inline-4
3-Speed AutomaticTransmission

I bought this Vega GT in Pa. in 1986. spotted it on the way home from Super Chevy Sunday car show in Reading.
22k miles. The engine cylinder head was off. I towed it home on a return trip. The rust-free GT had been repainted in its original color. I swapped the rebuilt sleeved engine from my first Millionth Vega into this low mileage automatic. Later sold the car to a friend to help pay for my second Millionth Vega special edition with 25k miles found in Hemmings Motor News. (see my garage)
