Rendezvous is an awesome name as it really does befit the vehicle - a meeting of a car, a van, and an SUV.
The other names I could go back and forth on, but the real disappointing thing to me is all this talk about Buick being Lexus and so forth. Perhaps its just me who realizes that Lexus was the Japanese Buick and I say that with complete sincerity and belief. To borrow from a George Jones song, Buick was premium before premium was cool. It was the poor man's Cadillac - and that's not derogatory. It had the style, the class, the panache of a full-blown luxury car without the haughtiness and especially the price tag. And though many Buicks approached Cadillac price ranges, the vast majority delivered a truly 'premium' ride for a bargain price. Even as recent as the late 90s, there were Buicks that lived up to that reputation.
The Century is derided by all for a 'wheezy' 3.1l and 'stodgy' styling, but remember this was a car that cashed out at significantly under $20,000 at a time when that price was shared by midlevel intermediates or stripped midsizers with 4-bangers. Besides, a $20k Camry or Chrysler then looked like a $20k car; Century didn't.
Regal GS set the standard for horsepower in midsize cars back in 1997 with 240/280 from the blown 3.8l. Remember what else had numbers that high for under $30k (loaded, btw) in 1997? Not Acura's flagship RL, which was 70% more and had far less performance. Not Nissan's flagship Maxima, which was a little more with a LOT less power. For an affordable sleeper, Regal above all others.
But back to my point. Buick doesn't need to be Lexus. Let Lexus be Lexus with boring, derivative styling, high pricetags, and a total lack of personality. Where is all the talk about Buick being B-U-I-C-K?
