I don't think buick used a full carpet in '52, I know Chevy did not, they had a rubber mat, with an optional throw rug for the rear seats.. in any case. my '51 Chevy is going custom, and I needed a carpet as pure white as I could get.. no auto supply had it, so I went to lowes and bought the most flexible straight cut white carpet I could find.. 25 year gaurentee too ( no stipulations that it has to be in a house, I checked ).. I think it cost $94 on sale, for a 16X12 section, that is more than enough to do the interior and trunk
