Nice original 73 RS Z28
 

This looks like a nice original 73 RS Z28. Other than the Z28, RS and AM-FM options this is a low option Z28 with spoilers added after it left the factory. https://www.ebay.com/itm/28465850071...53.m1431.l2648

Wouldn't the RS option be an add on too since it's a 03B car?

To the best of my knowledge, the RS option was available the entire 1973 model year.

Seat material would definitely not be my choice. Regardless, if it was a 4 speed, I'd probably be over there looking at it today.

Learn something new every day, thanks Bill.

Wow, the seats are butt ugly. Oops, I'm being opinionated again.
And the paint is about a 30 footer. The dry application orange peel on the left fender alone is a turn off. The whole front clip appears worse than the rest of the body. Maybe painted separately ?
