Im learning but i have talked to alot of old timers mainly my grandpa, who has dealt in salvage for years, The rarest of 49 are first: the hearse that was a special order item, The woody roadmaster, the super woodys were alot more plentiful and there are some out there mainly surviving in california arizona, dry regions, Then of the 8,400 production modles of 49 after say 3 months in the year the designer "not Earl" his wife liked driving the convertible but prefered the top up, So they desighned the riviera coupe that was basicly the same body as the convertible, but postless, at this time the same chrome was added to the convertible, so half the roadmasters have the chrome with spears and half without, there were just a few 2 dr cars that were built early in the year that are roadmasters but do not have riviera trim, and they have the same window as the roadmaster 4dr. The balance were very popular cars The fastback and super convertibles were popular with gi's of the era, and grampa said there were well over 5,000. of super and roadmaster cars produced in 4dr modles for family cars, i just purchased a roadmaster convertible and there are not many leaft some in yards but many have fell aside to build new suv"s, a couple of neat sites to check out are shimmer.com and sunbelt.com
