CL65 - unstable at speed

I'm looking at a '05 CL65 W215 with 11K miles. Love everything about the car. Only thing I have a problem with is the car seems very unstable when doing a hard acceleration, especially speeds > 90 MPH or so. At full throttle, the car rocks back and forth laterally...almost scary. Guessing the stability control is trying to offset/correct the torque from that beef-eating motor. The car is stable at most all cruising speeds. Is this common?

Also, price is 105K...seems like a good deal according to KBB and NADA.

Have you seen the Top Gear episode with the CL65? They were driving pretty fast and in the rain too. They didn't complain about any of that.

That might be the reason the owner got rid of it and the reason for the reasonable price. As a rule if a dealer is offering a resonable price then I get extremely suspicious, only good reason might be if the dealer had the car for a long time and really wanted to offload instead of taking it to auction.

This is a private sale, owner has cancer and selling off several exotics. It's still under full warranty, so not overly concerned about a mechanical problem...that can be fixed. I'm more concerned this issue is in the nature of this car. But I don't know, I'm a noob to a car with power like this.

Did you set the ABC and Airmatic right? That may be why the suspension was a little soft.

I think I tried both positions, but will try again. I thought the ABC was more for cornering/twisties rather than straight-line though? Here's a couple pix since I'm here...

You're right, ABC is more for that, but it probably would help a little.

Beautiful auto Lotus, I'd practically commit a homicide to have that vehicle.

Just an uninformed opinion here, but I doubt that AMG and Daimler would release a car that had too much torque for the suspension, tires, wheel size etc.

However, isn't this the 1st year for the AMG 65 power plant? It might be that there are a few bugs to be worked out, but I wouldn't be that concerned with those.

If you think the price is fair, you really want the car, AND you have the full MB factory warranty, I'd buy it regardless of the handling problem. Let the Daimler warranty fix it to your satisfaction, OR sue them for your money back if they can't do that

I would turn off the ESP (ABC?) and set the ride to sport (#3). That might make a difference. Also, remember that cars, even MBs, are designed for optimum performance between certain parameters. It sounds like your pushing it beyond "normal" use and that may also be part of the problem. I would have a certified MB shop do a complete check of all the systems.

Don't believe everything you think

90+ mph is certainly not being pushed beyong it's 'normal' use. These cars were built for autobahn cruising, and 90 mph is not autobahn cruising speed.

And turning off ESP wouldn't really do anything to help with the 'bounciness.'
