[911Etarga]

I am wondering what a '71E targa would be worth.
The engine is rebuilt-2.2E with carbs,
915 trany,
Paint is a 7/10 dark red(original color is light yellow),
No rust, straight body,
Interior is original S trim in OK shape(6/10-one small crack in dash, a little tired)
S calipers...
The car is a 7/10 in general, with a rebuilt(newly) engine.

Any guesses?

I don't have any pictures yet, but soon.

Thanks!
