Ugh, the weight disappointed... F-Type looks much smaller and lighter than it actually is. But whatever, I would take the Jag over any Aston V8 any day.
I've seen a comparison test F-Type V8-vs-V8 Vantage Roadster-vs-991 Carrera S Cabrio by Chris Harris, and the Monkey had LOTS of fun driving the Jag, even round the track. The wildcat looked so aggressive and swift! Oh, and that thrilling wild sound! And the looks! I'd drive that baby round the track all the day!
For a while Jag seemed to me as a favourite, but then I remembered about the Porsche. Porsche is also very exciting in its own way - maneuverability, German quality, Boxer6 sound... And it is the fastest, as expected. I love both 991 and F-Type, so cannot tell what car is a total leader. Aston is also a good car, but it's too old already and slow, and too expensive.
Of course, Jag F-Type V8S is not built directly on performance purposes. But if you want a performance oriented wildcat, like I do, then you're lucky to expect the F-Type GT. Rumored to generate 600 ponies and lots of downforce, and to be on diet! Oh, I'm so willing about that Jaguar supercar!
