The Mercedes CL63 AMG  really feels like the big luxury brother of the CLK 63 AMG. personally I like the cl more the clk but. it has more presence I think and a better stance.
this is also the most good looking CL model I think. the interior of the car is just beautiful. and even better then the S-klasse I think

this Video is al about the 3e generation CL-class  Mercedes CL63 AMG.  this is the first generation cl63 amg so with the very nice NA 6208cc V8 producing 525HP and 630NM
this car was for sale at  this company is a specialist in rare youngtimers and classics or/and low mileage cars
here is a link to the website have a look for more nice cars

here is a link to the car

This car is the perfect package.
it is just complete.  you got space for 4 people that can sit very good also in back.  it is fully loaded with luxury. it drives very good also for comfort driving but in sport mode also a very good suspension for handling in the corners.
the engine is the same is in als the c63 amg models only the power delivery is different this car is making 525HP and 630nm and is capable of getting this car in 4.6 sec from 0-100 klm h
that is realluy good for a car that is eight is 2085kg empty
it is connected to a 7 speed 722.9 transmission that is still a automatic with a torque converter and not yet with a MCT clutch setup. but still pretty good.  it is still fast enough for me.
this model is build from 2006-2014 in 2010 there was a facelift and also the 63 NA is change for 5.5 ltr bi-turbo engine.
but this is still oldschool NA engine with the very nice sound of a NA engine .
i really liked it.

if there are any questions  just ask

A pretty complete list of engine problems and most common can be found in this link to FCP EURO or below  

Common Issues of the Mercedes-Benz M156 Engine:

  • Crankcase Breather Valve – The crankcase breather valve fails in two main ways. The first and most common is that the diaphragm on the valve itself deteriorates. The other failure method is that the hose from the crankcase to the valve becomes brittle and develops cracks. Deterioration of this assembly leads to increased burning of oil, misfires, and heavy smoke from the tailpipe.It is common to have a fault code (P0170) that is for fuel trim.

    A general maintenance interval for your crankcase breather valve is right around 60,000 miles.

    To replace your crankcase breather valve, it’s necessary to remove your intake manifold in tighter engine bays such as the C63. This job should be able to be carried out in about thirty minutes. Although some use this opportunity to install an oil catch can system, we do not see many of these vehicles suffering from excessive oil in the manifold or sludge behind the intake valves.

    We have an affordable kit that addresses all of the components you will need to replace when replacing your crankcase breather valve.

  • Oil Leaks – The most common source of oil leaks on the M156 are the valve cover gaskets, camshaft solenoid cover gaskets, and oil filter housing gaskets. Valve cover and camshaft solenoid cover gaskets should be replaced concurrently. If these oil leaks are left unattended, they will damage peripheral components such as the alternator, drive belt pulleys, drive belt, air conditioning compressor, and transmission cooling hoses to name a few.
  • Drive Belt Pulleys – All of the pulleys on the Mercedes-Benz AMG M156 engine are a plastic design with a pressed on bearing. Although idler pulley failure is common across most Mercedes-Benz platforms, we recommend checking pulleys for failure symptoms at each oil-change interval. Pulley failure will damage the drive belt, and when that happens, the belt typically damages the coolant breather port on the thermostat. If you let that happen, you will have to replace a thermostat, and thermostat breather line in addition to the drive belt components.
  • Cylinder Head Bolts – Most Mercedes-Benz AMG M156 equipped models (up to model year 2012) have cylinder head bolts that have the propensity to break,allowing coolant to enter the combustion chamber. Early warning signs include a low coolant light, misfires, and a check engine lamp. We recommend all engines equipped with the older design bolts be updated. The cutoff for engines not affected by this design flaw is serial number 60-060658.
  • Camshaft and Hydraulic Lifters – Camshaft replacement should be considered a regular maintenance task as most camshafts show wear failures around 100,000 miles. Wear occurs most commonly on the left and right intake camshafts and if left unattended, the cam lobe will eat through the hydraulic lifter. Frequent oil changes, using the correct oil viscosity for your climate, and including an anti-wear additive with oil changes are all measures we recommend to protect your engine. Additionally, higher mileage engines should have their oil sent out for analysis periodically or the valve covers should be removed and camshaft lobes inspected for signs of wear.
  • Intake Manifold Failure – The intake manifold on the M156 is constructed of a cast magnesium alloy, contains an adjustable length runner assembly, and houses the engine’s twin throttle bodies. The center mounting plate that houses the throttle bodies deteriorate causing rough running particularly at idle.
