Lotus is currently developing a brand new 2-Eleven called the 3-Eleven, and if it's going to be faster than its predecessor, we're in for a good one.
If you're looking for a track-focused sports car that's significantly lighter and cheaper than a Porsche 911 GT3 RS, but faster than a Cayman GT4, you can get a single-seater BAC Mono, a nice Radical, the even-crazier-than-last-year Ariel Atom, a brand new Zenos E10 or whatever Caterham is cooking up at the moment, just to name a few.
In other words, your possibilities are pretty much endless thanks to the British car industry. Then, you can take your pride and joy to the slightly wet Spa Circuit in Belgium to show fast hatchbacks and the Eau Rouge what's what.
It's funny how you don't have to make a car light if it was light from the start. Think new Miata.
