Welcome to the site!
Sorry, don't know about SoCal.
If you mean road circuit track car vice drag strip track car... Phoenix Performance, the guys that prep about 50% of the SCCA T1 cars have a dedicated driver and trailer. They regularly pickup and tow customer cars across the country. Their shop is just outside Philadelphia.
They prepped my car for SCCA T1 last year and I have been very happy with the results.
I have their number if you are interested.
