Catwood,
There is a place in Newport Beach that has a SRT for rent. Unfortunately my computer crashed this week and I lost all my links. The guys there are really cool. I flew down there two years ago to rent the SRT with my buddy in OC and the person who was suppose to return it the previous day never did. That was a story in itself, but we ended up getting the 355 spider for the same price as the SRT. $1,100 a day for the 355 vs. $450 (i think) for the SRT.
I think this guy is located on the PCH just south of HB.
Good luck.
Steve
