Both cars have their attributes and faults. I have not owned the OFNA car, so I have no opinion on its reliability. I currently own both the IGT and IGT2. Outside of the 2nd gear issue and engine reliability issue of the original IGT, it has been a great car for me. I have a sound set-up on my IGT1 (which I race regularly) and before the Ipanema tranny upgrade, the only change I made was replacing the GXR 28 with a Sportwerks 26ps and header, using the stock pipe. In my area, the OFNAs and IGT2 with engines more powerful than mine can't touch my IGT1, even with its faults. If you don't set the car up properly and learn how to drive it, it doesn't matter which one you get, you will not have much success, period.
