It still starts with a database or secure web-page like you've been putting together. Maybe a few more fields but I don't think any of the registry's capture info beyond the following: vin, color, mileage, coupe/convertible, place of registration, owner name and address, date acquired, condition, amd modifications. For a small fee used to offset the cost of upkeeping the database, owners are issued a certificate of registry that memorializes this info and the vehicle is listed in the SRT-6 Registry. Most of these kind of certificates are just put together in MS Word and printed on decent paper. That's a non-issue.

If you want to gauge interest, suggest starting a thread as to how many people would pay a nominal fee for a more formal certificate of registry (and access to the registry database). What additional info would they like to see preserved?

The math is pretty simple -- if 1,000 people pay five bucks a head, that's $5k available to defray the cost. If the database is done in HTML (web non-sense), registry subscribers can be given access as well. I'm sure there must be a bunch of motivated forum members in that business.
