The longest of the '90s Cadillac Broughams were 225 (18.75 feet). No production Cadillac was ever 22 feet long; the longest were the '74-'76 Cadillacs at 252.2 (21 feet). The longest American production, non-limo car I've heard of is the 1973 Chrysler Imperial at 235.3 (19.6 feet). wooh!I think that one is in guinness book of records. Well In the present day cars , I think few lincoln cars are really long as compared to others !
