Ninety-Eight Regency will hate me, but I see Satty's point. And I absolutely love Oldsmobile -- I grew up with them, they were my first cars and I was hoping that there would have been an Intrigue around for my next purchase. $h!, when the announcement came out on TV, my stomach sank and I thought "no sitting at the dealership checking the boxes on an order form to get a sexy Intrigue just the way I want it." A very glum feeling, indeed.I maintain that the problem was duplication. Yes, as Bobo says, Olds was the purveyor of innovative design. That ceased by the time the 70s rolled around - purveying a POS diesel conversion did not help much, either. But, by the 70s and 80s, they duped virtually every Buick model on a 1:1 basis....Toro to Riv, 98 to Park Avenue, 88 to LeSabre, Intrigue to Regal, Ciera to Century, etc...you get the idea.
Mind you, I would say that each Olds model was always better looking than its Buick counterpart and I would always opt for the Olds model handily. However, they must have done their research and concluded that the curtain would fall on Olds and not Buick. I think all of the other divisions are readily identifiable - Cadillac is clearly the top of the heap, Buick is upper middle class luxury and quality, Pontiac is sporty, Chev is the "apple pie" baseline and Saturn is the brand with Japanese sensibilities and styling cues (more so than the others, anyway). If Olds was around, it would have been just like Buick (upper middle class luxury and quality). Now that is duplication.
I think GM is getting better. I can forgive them for the demise of Oldsmobile....sad as it is to acknowledge.
