The Jaguar E-Type is a convertible in Nice. Like the Ferrari 328 GTS you can only get this car in your menu by driving them in Nice's second mission, Smash and Run. You can't get it, even if you find it among traffic, without completing the mission. This car can drive really fast. It is a quite common car. This car isn't Nice's only convertible. There are more. When driving the Jaguar E-Type other people will appear driving it too.
