If my memory serves me correctly this is a first car for you right? You were considering a used mail truck for awhile as well. For a first car i think this will be a nightmare, get something that is cheaper & easier to work on. Im probably a broken record here but might i suggest a 2000+ Hyundai Accent or Elantra? They can be had for cheap, they are dependable, cheap / plentiful parts, and are easy as pie to work on. If you get the hatch back you will basically have a mini mini van that is capable of hauling mopeds (granted not the most idea way but its atleast more up to the task than that of a sedan).
Regardless, for a first car i would steer you away from German, Brittish, or French cars. Buy American, Japanese, or Korean cars for cheap dependability.
Or... you do seem to get alot of mopeds. Maybe a used Ford Ranger or Chevy S10 would be a good fit for you. Those can be had fairly cheap. I would recommend a Toyota but good luck finding a good deal on one that isnt rusted out.
