And as a follow-up to this post, since Oldsmobile is disappearing, maybe GM should take the 4.0L V8 from the Aurora, and stick it in the Park Avenue, and then add a fourth porthole; then give the other six-cylinder Buicks three portholes? That way they'd at least be (somewhat) consistent with older Buick heritage.
one porthole per cylinder. Now all older Buicks, or at least the ones I grew up with, were all 8-cylinder cars. However, 4-portholes was always reserved for the premium Roadmaster. I don't think we'll ever see "all" 8-cylinder Buicks again, but now that the Aurora is going, I could easily see that engine going in the premium Buick model, which is the Park Avenue.
I've never cared for models that small. I've never found the detailing to be very good. It's just too small to get it right. Although, these models look pretty good for 1:43. I much prefer a larger 1:18 scale model.
BTW, I saw in London in Sloane Square, a few years ago, a gorgeous British Racing Green Jaguar XK SS, like the model displayed.
