Check out lowcost-builder.co.uk and the kit car section on pistonheads. Its full of good advice.
They are a highly rated car, designed by Jeremy Philips and closely related to the Sylva Phoenix. They have two chassis weights. The lightweight is for track and has been known to break with very powerful cars on road. They also have various bonnet and body styles, and screen options. They have a choice of live axles or independent. The uprights are escort or capri, hubs were escort. Pedal box is tiny as mentioned above and require driving shoes.They are / were prolific winners of the 750c motor race events.
To be honest I loved mine but it was getting on a bit and I just didnt have the time to invest in it.
There are loads of videos up on YouTube...some by ahem myself.
Handling wise they are very well regarded and very easy to drive on the limit, they are also alot more aerodynamic than the seven style cars and so don't stop accelerating past 100mph.
I sold mine 1 month ago.
