I just found out, to my astonishment, that the Regal GS's seats do NOT have a lumbar control. I had my heart set on buying one this fall, but since the GTP seats DO have a lumbar control, I may change my mind. However, a guy in the Regal topic said the absence of a lumbar control doesn't really matter to him because his Regal GS seats are already very comfortable. Any comments?

Depends on what you want. The Buick Regal seats seem to be more of a "cushy" seat that you sink into compared to the GTP. I like my GTP's seats. Although firmer than the Regal's, they are very comfortable and seem to "fit" me better (I'm 6'1", 190 lbs). Lumbar is good on long trips, but I tend to set it, forget it when just riding around locally.
#43 of 4431 Ruski's suggestions/ride by vcjumper Jun 07, 2000 (6:39 pm)
I don't think any of the things Ruski mentioned stiffen up the suspension in a straight line (unless you get tires with a lower profile or stiffer sidewalls). They reduce understeer/lean in turns (thicker sway bars, polyurethane bushings) and lessen the effect of body flex in turns/over bumps (strut tower bars).

The thicker sway bars will result in more left to right pitching of your head when going over one wheel bumps and dips. The urethane bushings will transmit a lot more of every crack and expansion joint in the road. Same goes for high performance struts.

I never drove a Regal GS but my '96 Buick Riviera's seats were very compfortable. Although they had lumbar support. Buick is known for compfortable seats (but then BMW guys will tell you that their cars' seats a much better because they are firmer). Grand Prix only has lumbar support for the driver's seat. Also only the driver's seat is heated. The power lumbar support is 4-way which is nice. I just drove my GTP from NYC area to Fort Lauderdale, FL - the trip was 20 hours and I felt very comfortable with the car's seats as well as with the rest of the car.

My Regal GS's seats are very comfortable. In fact, I've had people almost fall asleep just on short trips. You just kind of sink into the seats like a recliner. They don't really look very supportive, side bolster wise, but they hold you surprisingly well while cornering. Mainly because you sort of sink into the seat. I have never sat in a GP so I can't tell you the difference. http://www.geocities.com/gs96_2000
#47 of 4431 Front end by tdheim Jun 12, 2000 (6:36 pm)
I have a 99 GTP with 10k miles. I have noticed a clunk/clank that appears to be coming from the front end on minor bumps and rough roads. Sounds like a bad rubber bushing somewhere,but it seems rather early in the cars life for that. Anyone experience something similar or is there a bulletin out that anyone is aware of for the 99 Grand Prix with regard to front end noise.

I have a theory - does your GTP have an HUD? My HUD has made a clunking sound when going over some speed bumps at certain speeds.
#49 of 4431 . by mrivers Jun 12, 2000 (10:46 pm)
I had a clunk due to a "misaligned" motor/tranny mount. It clunked randomly, until I took it to the dealership, who suprisingly enough, knew exactly how to reproduce it. Reverse + Hard on the gas = Clunk, since the fix it's never done it again.
#50 of 4431 tdheim- Front end noise by eblum Jun 17, 2000 (7:46 pm)
I had the same noise on my 98 GT from 4,000 miles to 40,000 miles. DO you know how to fix it? Have GM buy the piece of crap back... THe front end noise was just one of over 12 problems I had...the dealership, Davis Pontiac in Richboro, heard the noise (around 37,000 miles...they finally took the crap out their ears one day) and wouldn't fix it... GOOD LUCK!!!!!!
