KappaSphere does. They have built their business on these two cars.
I go to KappaSphere quite a bit, and I've studied their Lotus pretty closely. It is
very different from the SKY.
To me, the biggest differences are:
- Size. The Lotus is teeny-tiny and very cramped
- Comforts. The Lotus interior is very "Spartan"
- Focus. The Lotus is a track car you can take on the road; the SKY is a road car you can take on the track
Those are three very huge differences. I would not want to take day trips in the Lotus as I think it would be miserable, whereas in the SKY day trips are delightful.
