I had a 53 Ford convertible with a continental kit, a 1969 mustang fastback and an 89 Mercedes V8 roadster.
The first two are long long and I turned in the 89 Mercedes on an Acura RDX. I really loved the Mercedes but the cost of repair was astronomical. My Gen Z grandson adored that car too and it was really fast but alas the repairs, sometimes 4 grand a pop.
I still have a 78 Fiat Spyder but it is a four-cylinder and no way a muscle car. Really cute, though.
And long ago I had a 59 Karmann Ghia, another cute four-cylinder.
I have a 79 Fiat convertable w/a 5 speed shift. Beautiful design,fast,and fun. I don’t fit in it as well as I did back in 79 though.
