There are still many of those beautiful Buick straight 8's out there for sale. Condition, don't know. But they were one helluva an engine. My Dad always drove Buick Roadmasters w/straight 8's but he broke my heart when he bought that '53 with the V-8!
My all time favorites though, were the straight 8 Packards. I had a '41 Packard LeBaron which would wind out, with patience, to 85 MPH in SECOND!
What a rip!
The gals called that car "Dreamboat".
It had straps on either side in the back seat....to hang your shirts on......
