I got a little gung ho the past week and bought all of these over a couple of days because I couldn't decide what to get, but i finally made a choice so I'm selling these.
All 3 cars are RTR, and BRAND NEW untouched. I didn't want to open the boxes and play with them until I could figure out from the forums which one I'ld really want to own and keep. (Of course, most NORMAL people figure that out first and buy later

)
