257/365 – One of my favorite Hot Wheels because the body comes off, making it possible to interchange with other wheelsets, such as the one on the Retro series version from The Italian Job.
115/365 – I was fumbling with it the other day after I bought it, and saw a tab underneath that implied you could open the car. Sure enough, I was able to pry the body off. Really cool casting, I wish they made more of them like this. Would make customizing so much easier (not that I have done any of that yet).
