While there isn't much visual differences between the CL500,600,55 the 65 stands alone when it comes to power. The 604hp is almost too much for the rear wheels. I wish it had all wheel drive and was about 1500lbs lighter and was truly stand out that this vehicle cost close to $200K I was tempted to leave the window sticker permanently in the window. I also wish MB would not have put a governor on the vehicle it tops out at 155 where it still has plenty of room to stretch out to the 200 mark. I admit I don't feel 100% safe driving at the mid triple mark speeds b/c it is close to 6K lbs and would hate to have to try to stop or make a swerve If cash is tight go buy a BMW
The only gripe that I have with the car is that it does not come with a manual transmission. But I'm otherwise totally floored by this car, never have I had this much fun, the car can do anything. Track days (bye bye Porsche, Ferrari, Vettes etc etc, normal drives in the mountains and eats up the highways. Comfort second to none and no noise ever! I love it and will be buried in it. One car I will never let go of. Might be expensive but you can't put a price on the smiles / mile in this car!
When you want to step up to this level of car you will want to make sure everything works before you buy. Make sure to get a warranty also, (just in case). If you want a car that can transport you to the middle of next week "right now" this is the car your looking for. This car can break the tires loose at eighty miles per hour. Cornering is just as capable with the ABC able to keep the car level at all times. Luxury abounds as well. Key less entry, key less start, climate control, power sunshade in rear window, leather with wood trim, heated, cooled, and massaging, sixteen way power seats that I am very comfortable in just to mention a few goodies. So far after 5,000 miles I have had no problems. You will have to put in quality gas or the injectors will plug up. $120 for an oil change may seem expensive but it will be good for 10,000 miles which would equal what you would pay for three oil changes for the same distance. This year only made 52 so this is indeed a rare car. To buy one new would have cost close to $200,000, ($178,600 base price). You can buy one for a lot less now. A bargain in my book. Another "CL55" owner told me that the CL is the best model Mercedes ever made.
