My honest opinion: Run away. If the owner is "forgetting" things, doesn't know specifics, etc. who knows what else he's leaving out for you to discover down the road.

This sounds to me like someones half-assed hacked up "project" car. Buy a nice clean example, yes, they're out there, and start fresh (DSM or Evo). Get the maintenance up to date THEN mod it how you want it modded.
