I finally got my first expensive ship -- a slightly used Asp Explorer (that apparently was only used to deliver beer and fish if the smell from the cargo hold is any indication).
I've got it upgraded to mostly B-class with around 64 tons of cargo capacity. I've been using it as a light cargo courier. It's really bumped up my earning potential being able to take 3-4 100K+ "shuttle this to there" missions at a time. Bought it over at Aramil -- IIRC -- closest system to me that had the 15% discount.
Got around 150 LY away from the purchase system and started to feel the pangs of loss for my beloved Cobra mk3 which was left in storage at Aramil. So I flew my new Asp to my "home base" of sorts -- Vela City @ HIP 74255, rented a new sidewinder equipped with an A grade FSD and all the fuel tanks I could fit onto her and took her on a one way trip to grab my Cobra.
The Asp is a lotta fun -- priority parking at outposts and stations, decently fast, and fairly decently armed -- triple blast lasers on the small hardpoints and 2 level 2 overcharged auto-cannons on the medium hardpoints -- those were a pain to transfer from my Cobra. Got blown up real good in an interdiction from an NPC driving a FAS, but she seems to handle anything smaller pretty well.
