I traded a beautiful 1936 Packard 120 Touring Sedan, for a 1970 Mercury Montego MX Brougham with a 429 and a C-6 transmission. It had just over 43,000 original miles and was an original California car “No Rust” anywhere. It had a Marti Report that stated it was 1 of 41 with that engine and transmission.
It is a beautiful car and I won a “Nifty Fifty” with it at the “All Ford Nationals” at Carlyle, Pa.
It is fun to drive and still gets 17-18 mpg on the highway.
