Re: Most embarrasing cars of all time
The Chevrolet-Chevette.
Actually, I owned one, from 1978 to 1980. It was a Ralleye Sport model and it actually served me quite well.
I was in college and the only failure I had was a battery, after four years, since new. I put 40K miles on that car and sold it with 98K.
My favorite "pick up line" in bars was that I drove a "Vette". Not a complete lie.

Remember, this was circa-1978-9.
I cannot say it was a bad car, just an embarrassing one, for a virile guy, on the hunt and broke.
I have fond memories of that car. It would go where many 4 X 4's wouldn't. I hunted, a lot, in those days-for food. I had oversize "snows" on the rear. It even pulled a light boat. It didn't have enough power to get stuck.

It provided 35 MPG when I needed it. It was a three speed automatic that turned the engine 3500 RPM at 55 MPH. Did I mention, I was broke.
Thinking back, I have NO complaints.
