jaguar is still producing sportcars like they've done for decades

I disagree. Their only current models that I could consider sports cars are the XK8 and the XKR. While both are powerful cars, and probably fun to drive, neither is available with a manual transmission, which I'd say is a requirement for a sports car. In fact, the only current model available with a manual transmission is the X-Type, which is basically just a rebranded Ford.
