Dedicated track car

[dazzer]

Having completed my first track day at Croft has got me thinking about a dedicated track car. I have two in mind and would appreciate views from anyone with relevant experience or knowledge about my inital shortlist.

Ariel Atom
Radical SR3

If the cash machine allows I would like to consider the FI versions of these. I am prepared to get some proper track training also to get the most out of these. The Radical appeals for many reasons but in particular there appears to be more choice re secondhand availability and sensible prices - relatively speaking.
