Why should PD bother? The subtle differences of an Acura Integra and Honda Integra just isn't enough for most people. Who cares if the bumpers, taillights, and headlights are slightly different...if the cars are avaialble in both markets, why should the programmers bother to make an extra copy of the car for a few fanboys? If you're concerned with a 5-20hp increase, there's something you can do to the car to rectify that problem...it's called tuning, a hallmark of the Gran Turismo series!
