The HPI Accord was a popular race body years ago. The handling won't be as good as the new bodies out there that have had all these years of knowledge and development behind them, but it would still be a better than a truly realistic body.
Seems to me all the Protoform bodies are pretty good. From what I've read they all handle a bit differently, with some being more aggressive than others. The most aggressive is the R9-R, then the LTC-R, the Mazdaspeed 6, and then the regular Mazda 6 being the least aggressive. I'm not sure where the DNA would slot in there. Hot bodies also has some pretty good bodies, but I haven't tried them yet.
