If you open your legacy and under character perks click on Speeder Piloting III you can buy it for 225 Cartel Coins and train it at any level, even a brand new character. Since you bought level 3, you do not need to purchase level 1 or 2, they will automatically unlock. Now "almost" all speeders require level 10, but if you bought the collector's edition, or the digital deluxe and have access to the Longspur STAP it has no level requirement. So for the low price of 225 Cartel Coins (and the digital deluxe/CE) you can have a 110% speeder at level 1.
