Agreed. I have the United version too and I'd say he has by far the nicest looking alt mode in my classics collection. Love the flames and the red autobot symbols look very nice. Nice detailing for the mags, grill, head lights tail lights & exhaust too.
Only downside to me is I can't get the back half to sit 100% flush in alt mode. It always seems to be out by about 1.5 mm. Didn't think it was like that when I got him out of the pack, but can't recall for sure.
Nice bot mode, love the head. So G1 Tracks!
