Buick LeSabre Limited Collector Edition
This would be the final year for the rear-drive LeSabre before another downsizing and conversion to front-wheel-drive for 1986 (sedans and coupes only; the rear-drive LeSabre Estate Wagon would soldier on unchanged a few more years). It was also the last LeSabre sedan and coupe to feature body-on-frame construction, V8 power and Buick's traditional all-coil suspension (the 1992–96 Roadmaster sedans would also be similarly built). The top-line LeSabre Limited became the LeSabre Limited Collectors Edition to mark the end of an era for the rear-drive sedan and coupe.
Engine offerings included the standard 231 V6 (sedans and coupes) or optional Olds 307 V8 (which came as standard in the wagons) and Olds 350 diesel V8 (available in all models). 1985 307s received roller lifters for reduced friction.
Production of this generation continued until 1990 in Estate Wagon form, as well as some reportedly found as hearse conversions.
