Yes, remember the PA Cresta well!. My father had a 1958 model. Leather seats (bench seat in the front, driver + 2 passengers) rear window with separate quarter-lights and separate side-lights and indicators at the front. 2262cc straight-six engine coupled to a three-speed gearbox. Design was clearly American!
In late 1961 the model received a facelift which included a one-piece wraparound rear window, combined (white) front sidelight/indicators, redesigned rear lights, and IIRC, changes to the interior and dashboard. I believe the very last of the PA models were fitted with the larger 2651 engine which was used in the PB, which came out for the 1965 model year, in much the same way as the last of the PBs had the 3294 PC engine. (I had a PC myself for a couple of years).
All in all, a car way ahead of its time. Its main weakness was rust. During the period from the late 1950s to the early 60s, Vauxhall, it is said, purchased steel from a non-UK supplier which was sub-standard, and essentially, got stitched up. That is why the PA Velox/Cresta and the F-Series Victors rusted so badly. A real shame, as these cars were otherwise pretty solid mechanically.
