1970s Jagur E-Type

By the end of the XK140 and XK150 era Jaguar fans waited with anticipation to see what the company would come up with as its next generation GT car.

However, owners complained about inaccurate instruments, overheating, oil leaks, dodgy electrics and clutches which were prone to falling off.
