If it's the car I am thinking of on eBay, nowhere does it say that it is an original RAIII car. Without a PHS all claims are suspect, and if the engine is not original to the car then value is nowhere near what a numbers matching RAIII drivetrain would be.
RAIII is not a huge performance gain over a regular 400.
