I was 16 and it was early 1978.
'73 Chevy Vega GT. Looked like a hot rod to me. It was the brightest orange you can imagine, then I blacked out the front nose and rear of the body.
Also painted the door handles, had the darkest tint you could get and the wheels were black with chrome beauty rings.
The interior was perfect, if you could call brown plaid seats and baby puke yellow carpet perfect.
Amazing Sparkomatic hi-fi sound system, WITH AUTOREVERSE CASSETTE PLAYER and 4 triaxial speakers, maybe 5-10,000 watts according to the box?
Ran like a ruptured dog. 0-60 time was in the 20+ second range and top end was a terrifying 85MPH or so.
I had to add a quart of oil to the crank every gas fill-up. My brother called it the "clown car."
I paid cash for it (earned mowing lawns, etc.) and I shored myself up by saying "At least it isn't a Yugo!"
