IMO and that maybe worth 2 cent on good day. Buying a non cert car is bad investment,then racing usually is anyway. Harder to sale later and as said not as safe. As for making 40 w/o killingself.I made 47 same way and doing as much dangerous over the line crap as anyone.I contribute a lot of that being to taking educated chances. Ive been 5.7 at 249 in alky car way back in mid 90's. I would make a pass in non cert car,because to me the very slight cost differance is not worth it. Just my opion,but then I hat seat belt and helmet laws.
