The split bench was a big part of why I sprang for this one, you don't often see it on sedans. Strangely, despite this being a L-O-A-D-E-D car, it did not come with power seats, maybe they're more expensive with split bench. It DOES have the reclining passenger seat, which may have been standard on the split bench. I can tell those nice blue seats on yours were almost NEVER sat on or outside, as the fabric on these did NOT age well. We replaced some in both front and rear fabric and it matches the original real well.
Recently picked up an AM-FM (thumbwheel) radio for mine..... I wasn't wild about gold at first, but the original finish is still in pretty good shape, and I really like the contrasting white top. The blue color is fantastic on these cars, and yours is a prime example. Hope to see it in person sometime!
