Considering the pricing on the speeder piloting 3 being that low, it's not much of a surprise of something there not being wrong.
It's not low anymore. Speed Piloting prices were dropped in game with the patch. Speeder 1 for example is only 200 credits. Speeder 3 was dropped to 150k I think.
To compare, Rocket Booster is 250cc and it costs 2.5 million credits to buy. (Speeder 3 account wide was 250cc I think)
