Considering R300/400/500

[Jeff101]

After getting a lap in a caterham at the 'Ring I think I need one in my life!
Sadly it involves getting rid of my Exige S but it is time to move on.

I am starting to do my research looking at specs, maintenance and prices etc etc. I think I have settled on an R400 K but could be swayed either way.
Will be used for fun with 1-4 trackdays a year. Have decided I definitely want a cage, just in case but think they look good too.

So what do I neec to know?

Appreciate the help and finally is this an R400? It doesn't have a stack dash which I thought they all did. It's also a very bad advert but does anybody know the car?

R300 to R400 spec? And they want R500 money. Not so sure his business will take off if he buys that kind of stock.....
