Touring car advice needed please

[HOTSHOT III]

I usually race outdoor off-road but recently i've found myself becoming sick and tyred of all this endless warm sunshine(not) so am looking into racing touring cars on carpet indoors. I've never raced on-road so any advice would be appreciated.

Modelsport are doing the Schumacher Mi1 for £125, would this be a good beginner's car? Am I right in thinking it's the same as the original Mission from circa 2000/2001? Are there any alternatives in about this price bracket? I don't really want to spend a fortune just to find out if I enjoy it, but I do want to start off with a new car and build it myself.

I have a 2.4Ghz radio and servos I can use so no problems there.

Also I have an MRT VX Pro and an LRP V7.1 speedos sitting doing nothing, along with a couple of (new) Reedy 8x1 brushed motors (If these sound a bit aggressive, both speedos have power limiting facilities). What race class would these motors put me in?

What kind of figure would I need to budget for trying different tyres etc., bearing in mind I probably won't have the sensitivity of a seasoned TC driver?

This is all a bit like black magic to me so thanks in advance to anyone who responds to this and points me in the right direction.
