A Canadian-spec 2011 Mercedes-Benz S450 recently came up for sale in my area. It looks like a great car. However, I am concerned about parts availability, especially for the 4.7L engine and driveshaft. From my limited research, the major differences are:
4.7L V8 engine, 335hp, 339 lb-ft torque
4-Matic standard
130mm (5") shorter wheelbase which drives unique body structure &rear doors, unique interior trim on rear doors & carpet
No rear zone for heating & air conditioning
Slightly better rear head room (5mm)
I am not a M-B expert. What other vehicles is this naturally aspirated 4.7L V8 used in? I'm concerned about spark plugs, coils, normal consumables
Can someone educate me on the standard content of the S450?
Here are pictures of this 2011 S450:

Reason: more info
Information on the S450 in Canada is sparse. I found from Good Car Bad Car (https://www.goodcarbadcar.net) that approx. 1000 S-class and CL-class combined are sold in Canada annually. I think this leaves the S450 to be a low-volume vehicle for North America.
NAPA's website (www.napaonline.com) does show the S450 as a selection. I compared some consumables and found the spark plugs, coil packs, air & oil filters are shared between the 4.7L NA V8 and 5.5L NA V8. Front brake corners are shared between S450 and S550. That is good news. The accessory drive belt and tensioner are different.
Rebuild Master Tech shows the S450 is equipped with Airmatic air springs.

Reason: Additional Information
I thought about getting an S450. I couldn't find one with a leather interior. A plastic dash and door panels just sucks IMHO. A leather interior should have been standard on these cars. In the end I bought a long wheelbase car so I could get a decent interior. It's that MB tex stuff. A leatherette. It wasn't even Designo either. Just the mid grade interior. It looks like leather.
