1970 challenger 340 6 pack TA

I found an all original number matching
340 6 pack car. This car has been untouched. It is rust
Free with all original paint.

The car is complete. It is yellow with a brown
Vinyl top. I took a pile of pics. It is a 4 speed car
As well.

This car is mine if I want it for $30k.

I am a novice with Chryslers but I really trust
The seller. He has the build sheet and window
Sticker.

I have an idea of value but don't know everything
I should be looking for in a 340 six pack TA.

I also would like to know if original paint cars that
Are really nice being more than what the value
Guide displays for this car.

Any help would be greatly appreciated!
