Yeah, but that color isn't in line with the mid 70's. I'd say late 50's or 60's. Grills were easy to make "trendy" with the change of the paint color. (Remember the hunter green ones from the early 90's) I would think mid 70's would be orange, red, black, bright yellow, chocolate brown, etc. A green one from the 70's would have most definately been avocado green. With that lime green color that grill is definately a 50's or 60's item.
As far as not buying it, I would not feel bad. Once it is used it would never be the same again.
