While I would agree it has a lovely profile, anything but that view highlights the E-Type’s awkward narrow tire track. For Jaguar, the XK120 did it for me, especially the coupe over the convertible.
For 50s though, I like the Austin Healey 100/4, Le Mans version with the raked windscreen
60s - 289 Cobra
70s - Ferrari Daytona
80s - Audi Quattro
90s - Mazda RX7
