If you don’t mind making your own templates, and checking a table for the skid dice instead of using the custom ones, I think it’s worth dropping some cash on the rules. It has a bit of a Car Wars vibe to it, and it’s a great excuse to go shopping for Hot Wheels and Matchbox cars. I love that the entry level for this game is so cheap.
I never really got on with Machinas. I love a lot of the THW rules, but that one did not appeal as much as I would have liked.
