It's a small car so what do you expect. That said, my biggest gripe against the Cayman was how claustrophobic I felt when I sat in it, which is why I pretty much gave up on that idea and shifted focus to the 991, so hopefully the F-Type isn't that bad.
And on the topic of Rover, my last car was a Range Rover Sport and if you have experience with those, you'll know that they have one of the best driving positions of any vehicle out there (in terms of visibility, etc), so coming from that into a small sports car is a big adjustment.
Never in a million years did I think I'd be in my mid-to-late 20's and considering a Jaguar. How do they lease? On the Jaguar USA site, I'm seeing $800/month with $5k down for a base model and you have to pay for excess wear & tear. Not great but not terrible. In Canada, this means $1,200 with $10k down though
