One of the reason that I change from Serpent to Mugen was because of parts, almost 80% of the people that race at my local track runs Mugen, the store is close on Sunday which is the race day, and if something come up, I can always ask someone at the track for a part and finish the day...
Performance wise, the cars for me are the same, is just depends on the setup that you got on it. and that's when it helps the tips from other racers.
