What class would a stock 300SD run in? I've been looking to run my MR2 as soon as I get new struts and fix the leak in the the clutch slave cylinder.

I would like to get my daughter involved in autocross to teach her how to drive well, but don't want her learning how to drive a stick at the same time. Seems like my tank would be a perfect car for her to start out on. I don't think she could hurt it.
