Sounds like the 70’s junk.
Who can forget your neighbor’s Grenada that detonated so bad it sounded like a diesel?
My very first car was a brand new 1977 2-door Ford Granada with the 302 V8. I have now owned 19 new cars and two used cars (one inherited) and that Granada was the only vehicle that I never had to take in for warranty work. That 302 was great.
