GL550 driving impressions (somewhat long)
Pros:
1) Engine: when the sales associate was taking us out, he gunned it and I was thrown back in the seat. When I took over, the response was good but not as great. I attribute this to my tentativeness on the test drive; I'm pretty sure that as the car and I get to know each other, the performance will be just fine.
2) Transmission: see #1 above. Very smooth shifts.
3) Brakes: some reviews have complained about the brake feel, but I had no problems with it. The stopping distances were quite short for class.
4) Ride: like a sport/luxury sedan. The ADS is very effective, with a noticeable difference between settings. Interestingly, I found Sport to be adequately comfortable for most road conditions. However, it's nice to be able to offer that smooth comfort ride to passengers on long trips. Also, absolutely no penalty in harshness with the 21" wheels.
5) Body: in the metal, the differences are noticeable but not as pronounced as some of the publicity photos would indicate. The AMG wheels are very, very nice. Overall, the look is aggressive and sporty, but not at all blingy or garish. A nice upgrade.
6) Handling: steering is lighter than the 3 S550's I have driven, but with better feedback. The effect is sporty and nimble, and the vehicle handles like it is 2000 pounds lighter than it is. I don't know how Mercedes gets this level of handling without a ride harshness penalty, in a vehicle of this size. To me, this alone justifies the $80K price tag.
Cons:
1) Leather: the same as other GL's. I was a bit disappointed in the plasticky feel. Perhaps with break-in, the seats will soften. Also, it is blisteringly hot in NC these days, and ventilated or at least perforated leather seats would have been welcome.
2) IR glass: would have been nice for heat control; not really needed for sound dampening as the GL550 is very quiet as is.
TBD:
1) Multi-contour seats: did not feel all that much difference with the different settings, but I did not have enough seat time to make a judgement.
2) Fuel economy: bound to be pretty low, but one has to pay a price for a vehicle with all of this capability and capacity.
3) Winter performance: I'm a little concerned with how the tires will handle the occasional winter weather we have here. My main justification to my wife for moving to the GL from a minivan was to have all-weather capability (to get me to work at the hospital). If things are bad with the standard setup, I will have to switch to winter wheels/tires (which I preferred not to do for the rare occasions we have slippery roads during the winter). This was a calculated risk; the overall package of the GL550 was too compelling to resist at this price.

Raj, Thanks for your input. In regards to the tires, I understand that these are M+S rated. Is it the tread depth and tire size that concerns you?

We're definitely
here from Raj's excellent feedback but I just couldn't resist. Apologies all!

And, Pewter/Mac is a beautiful combo. That was the first GL I ever saw and it has stuck with me.

I agree about the ventilated or at least perforated seats. I am going to give up some fantastic seats but as things go, you win some and lose some.
Thanks again sraj...so many doctors on this thread maybe BETO's remark about an ambulance had some merit...
