ron's great info shows:

1. In Georia: No title is necessary, or is issued, for older than 1963. (nothing about second owner, etc.).
2. Seems that Texas will accept a Bill of Sale as proof of ownership, then they issue a real Title. Classic or Antique or .... Some of the categories may not require inspection.
3. Sounds like you have a normal transaction. No funny business is recommended.

My input: Usually the kind of bill of sale that DMV's want, needs.
1. Signature of seller
2. VIN
3. Date of sale
4. Address of seller and phone number
5. Your name as buyer
6. Description of vehicle
7. Possibly purchase price
But who knows until you get up to the window at DMV.

I would not present or give them anything at first. Just ask all the questions. If you give them anything and it's no good for their purposes, the may keep it, or they may document a refusal. ALWAYS make copies of everything you have before handing to them. Lots of us have had good and bad experiences. Be careful what you say but be honest about what you do say. Get fully informed, straight from the horses mouth, before you actually apply.
Personally I would not get ANYONE else involved, such as a, so called, "service" or outside provider of ANY KIND.
