I remember those movies and TV shows well. They drove one off a cliff in Magnum PI.
It's interesting this should come up now. Peter Egan's article in the new R&T included some insight into the terrible habit so common in the 70's and early 80's.
He mentions that none of the mechanice at Chris Beebe's shop wanted to work on E Types. Back then you could buy an E Type cheap. Say $3K. Then you need some work like a clutch and the shop handed you an estimate for $1.5K. When you needed an engine overhaul it cost more than the car was worth.
I remember looking at several E Types for well under $2K in the mid 70's. I almost bought a 67 for $1200. It was less than 10 years old, in primer at a paint shop. Solid as a rock. I passed when an old friend who owned the G&L sports car lot and garage in Absecon NJ told me I might be able to afford a Jag, but "You can't afford to drive one".
Sad to say but he was 100% correct. Jags were cheap back then, but still very expensive to maintain. Of course AC Cobras, old Ferraries, Astons..... were all in the same boat. I knew a guy who bought a Healey 3000 for $50. He put in a new battery, tinkered with it for about half an hour and drove it home. At the same time you could buy a new TR6 for $3500 - $4000.
I still should have bought the Jag. Whether or not I would still have it.....? Although I do still have the TVR I bought in 1978.
