Don't fall into the old trap and think that to go faster and get nearer the front that you need to spend ever increasing amounts of money as you can't "just" buy your way to a race win (of course you may be the new Senna) !
To a point any half reasonable new driver can run midfield with a reasonably cheap but sorted car , with a bit more experience you can make inroads towards the sharp end.
The challenge is to beat the check book racers on a shoe string. A guy I know remortgaged his house to go racing, after a couple of seasons he lost his house and his wife because he became completely obsessed with it
