So what can be concluded after all this data about the current price for a T?
On a scale from 1-5 would this be an approximation (see below)?

5 - $15,000
4 - $12,000
3 - $10,000
2 - $7,000
1 - $3,000

$3000 is basically a rusty roller.

It seems like an excellent original T is going to be in the $20k or $30k range. The very best cars would be higher than that.
