I just put liability on my V8 car with the thought that there's no way I would ever be made whole with my insurance company so why pay for insurance for physical damage coverage for something they won't pay for anyway. It's only an $18K car so I'll take my chances. If I total it I'll build another.

Well you can always get a quote from trackspeed for a v8 swap and use that as a basis for your declared value. That way the insurance actually can rebuild you.
