Olds needed more time pure and simple.
I don't see how you can look at any of the new Oldsmobiles and really call them 'yuppie wagons.' Aurora and Intrigue did nothing but uphold Oldsmobile's tradition of being the spearhead of American automotive innovation with the aforementioned 4.0l V8, PCS on the Intrigue, and distinctive styling. The fact that Aurora competed very, very favorably against the Q, ES, and Legend/RL as well as the Lincoln Continental and blew away the LHS tells me that these cars had appeal that bridged wide gaps other GM products couldn't.
On a pure styling note, you can't simply brand them as 'jellybean.' Look at the Aurora for one. Note the composte headlamps, the clean grilleless front fascia, sculpted tail, wraparound rear glass, framless windows, and area ruled flanks. Even in generally smooth cars like the earlier 929 and later Taurus, the truly original detailing mentioned above is noticably absent. In those cases, you simply get a round car. In Olds' case, you get something distinct and original.
Also, look at the new Oldsmobile's ideas - the cute-ute Recon debuted in 1998. Imagine that hitting the lots in 1999. See ya, CR-V. Imagine the Profile making the rounds in 2000 and up for sale the following year. See ya, Highlander. And then the O4, showcased in '01 and being sold in late summer of '02. Beetle 'vert wha?
That's what would've kept Oldsmobile around. In fact, it was the very presence of gauche lameness like the Cutlass Ciera that hurt Olds more than anything. As far as geriatrics go, well, I wouldn't describe Marc as 'geriatric' - more, say, an older gentleman - but he loves his '01 Aurora. Alot of older folks really do have taste and don't just want a cheap, decontented boat with a ton of chrome.
