With enough Cartel coins and Legay levels, I was able to unlock the following on my ship across ALL characters: A mailbox A Vendor/repair-bot A Global Market Kiosk. Now if I need something, no more trips all the way back to the Fleet. On some as long as you have enough coins you can forgo the legacy level requirements. I found the hard way it's not worth the $$ to unlock speeder levels as they don't carry over to the Legacy, the fine print says "this character only" and I wasted the cash on it when I already had it.. there was no real warnings that I didn't need it. I'm at max level now going through the Revan expansion quests after finishing up Rise of the Hutts, these consist of a lot of solo flashpoints so far. Also backtracking unlocking missed DataChrons to give all my characters the added perks as well.
