You are very easily sold.

Check out the following locations.

You are always looking for Car trackdays, not test days:
http://www.trackdaylist.com/

They feature some good websites on there, the big one being javelin, but circuit days and book a track are also big organisers of trackdays, but anyone is good.

Also check out my personal favourite:

In terms of tracks, if you are in london then theres brands hatch, thruxton, donington, rockingham and silverstone all within range but they normally expensive.

Snetterton, castle combe, bedford autodrome, mallory are cheaper.

Price wise cheapest ive ever paid is

£65 for a ticket.

I try not to spend more than

£120-130 but will stretch to

£160.

Silverstone and some others can charge as much as

£300 for a day.

Always pay attention to what you are buying.

All day open pit lane is best value.

Half days and sessioned events are also offered.

Also factor in the cost of fuel

(1 whole tank on track and however much to get to the track and back).

Helmets are hired at the track for

£10 or you can get one of ebay for

£40.

Roll cage isnt required.

Also check your breakdown cover, most

(infact i think all) dont tow from the circuit.

Either pay the on site recovery guys to tow you down the road to then ring the breakdown company or do as i do and become a member of the ADAC.

They are german but contract the AA who dont care where you are as they get paid either way.
