Autocross doesn't do that to a car. Hell my truck gets more of a workout towing enclosed than my car would through the cones. Now the real question is did blue turd leave the tow bar on when he autocrossed?
False. Autocross can be hard on things. I've blown up a diff twice in the span of two events, saw multiple cars break ball joints at the same event, various broken suspension arms, many, many hub failures, engine failures, etc, etc
As for what I've towed lately

98 C2500 with the 5.7 and 4L80E. Borrowed a trailer last year but the plan is to pick up an aluminum 16 footer to pull the Camaro to autocross and M3 to time trials. Only real plan for the truck at the moment is some tow mirrors. Probably going to rent a Ridgeline from work for the 800+ milers though.
