one might argue that Gp2/AppK is cheapest, its supposedly production stuff, ie the way the car was built . . . it only gets expensive if you let it , ok you won't win a race in a std car but you can be in a race, properly, on a normal working mans budget (a lot nearer 4 figures than 6+ shall we say!)
IF you want to push it and go bespoke/extreme FIA it can get expensive I'm sure, and its pretty obvious that it gets very expensive for some ( especially when the prepper sees you coming in your german owned british marque!)
HRSR regs champion 'free' regs on most components, therefore inviting imaginitive and ingenious engineering and preparation, read potentially very expensive. That is highly commendable in its own way, its also completely legitimate and valid in a Gp5 and post 65/66 club racing kind of way.
the two are very different however, and IMO should be separate series, the HSCC could and I think should seriously consider doing this
tin tops are the most popular/entertaining spectator races, so while we're at it lets suggest a 70's rust race as well . . .BL racer anyone
