Newbie in Nashville

[Predsfan]

Joined today. Just bought a 93 w/117k miles. Red out/grey in. It came from Cali-1 owner with straight, solid, rust and ding free body. Pristine interior-never seen a 20 year old vehicle with an interior as nice. Sunroof, tow package, running boards. Has new tranny, but engine had Lucas already in it-and a sample showed those shiny metal particles. So my first decision is to rebuild motor or buy a rebuilt. Comments from the voices of the experienced welcomed. Advice on dependable efficiency mods also needed.
