You are off to a good start. The real trick is getting the support out without damaging the body. How did that go? You might experiment with printing the body in a more vertical orientation. Imagine the front bumper against the print bed.
Either way, finishing an FDM body will require a fair bit of"hand work". Traditional Bondo body filler and sanding is one path. There are other model making fillers as well (I like Tamiya). Smooth-On sells a product called XTC-3D that might be worth a look. On prints that came out really well, I've been able to just use spray can "automotive filler primer". You can find it in the paint department at most auto part stores.
