The CE speeder is just a free speeder. You can't use it until you reach level 25, and train Speeder Piloting for 40k. It saves you 8k for buying a speeder, and looks cooler (imo) then any of the basic speed speeders, but once you are able to use the faster speeders (100 and 110% speeders, with a chance to not get knocked off when hit) it's move speed doesn't scale--it has the same move speed bonus a regular speeder has (90% and you are dismounted by getting hit with any attack.) However, you do get one for each character created on the account, hope this helps.
