Switching models might be the easier way out for you, just remember to stick w/ similar vehicle types (2-door, 4-door,
bikes, planes, etc) & don't mix them.
I haven't made a serious effort to find the races in the MAIN.SCR file (over 1/2 million lines of code), but I also want to find
the section that controls races. In my case I want to make them "run what you brung" (like the races in VC & GTA3) & the
cars currently used become reward cars at some of your savehouses. If I find the section, I'll start a topic "SA races Code"
or similar.
