Hi there,

This is an offshoot of the South East Lotus Owners Club (SELOC). I have done a number of these track days and they get some great days at a really good price and the standard of driving is excellent. If you want to do track days then you'd be hard pushed to find better organised ones.

I will be doing some next year when the car is finished!

Rich.
