I just took a weekend jaunt of about 630 miles. Of course, I did not see every car on the road, but I did notice more than usual as I'm driving a new car and still looking at what is available and what I like etc.
I did see more Rolls Royce than Buick Lucernes. 1 vs. 0
The road was loaded with Altimas, Camrys, Hyundais, lots of run of the mill older GM cars, but I only saw one Lacrosse and no Lucernes. Not too many of the Fusion/Milan/Zephyr
One thing I did notice though, where the hell did all the Infinitis come from all of a sudden? I don't think I've wver seen so many as on this trip. Perhaps it is a regional thing, but here in CT/MA I just don't see all that many, but in NY/NJ, they were all over the place.
