Cheap track day auto

[Gibbi]

Can anyone recommend a cheap auto to use on track days (if there is such a thing lol). Due to only having one arm I'm stuck with driving an auto.its not a problem for my Dailey driver or even my weekend toy but I wouldn't want to track either of them. So I'm looking for a small auto that could be fun to use. I know it's not going to set any track lap records, I'm just looking for something to have a little fun in. I have looked at a couple of bike engine caterham style cars but just wanted to see if there are any other options.
