It looks like a good car at a great price. Way less than an equivalent '68 - '70 B-body. I would be hard pressed to sell my '67 R/T for same $$$. Value of '66 - '67's can only go up.
425hp claimed as "stock" in that 440? Somebody doesn't know Mopars apparently...
good looking car though.
By the way, it isn't actually for sale on CL - it's being auctioned on a website I've never
heard of: 1967 Plymouth GTX For Sale On Clasiq Auctions.
