hi i have three mopars and i was wondering on how rare each are. first i have a 1970 coronet 500 the vin number is wp23n0e120042. the car is f-4 with green interior and a vinyl top, not sure of what color (i believe green top)this is a hi-perf 383 n-code also a/c car , second i have another 1970 coronet 500 the vin is wp23l0exxxxxx. the car is original plum crazy with black interior and black vinyl top with an 8 track and a/c, last i have a 1972 road runner 340 car. the guy i bought this off of said it was a gold sticker special car as the exterior was gold. the vin is rm23h2g168319. this car also has a very odd looking interior. the guy that i bought it off of said it was an option called navajo interior. it has brown black gray and white stripes blended which looks like a blanket but it looks to be original and untampered with. anyone heard of this interior ??? thanks
