S 500
Exclamation Considering a S500 2006 Model

Hi everyone

Huge fan and been on here multiple times.

Cutting to the chase, I just need hints/tips for when looking at a 2006 S500 (5.5 Liter) (in a few days). Here's what I know at this moment:
  • 152 000km
  • $10,000
  • FSH, owned by a Doctor from age 71 to 88 when he unfortunately passed, hasn't been 'owned' since, being sold by the person who inherited it
  • I can see no issues from the listing pictures (attached)

Possible issues:

1. Falls in the Engine Code with the guide idler gear wear


You can look at the VIN/Engine number and you'll see this M273 engine falls slap bang in the middle of the error. I will only be able to tell on viewing whether or not this has been looked at, is there something *specific I should look for in the books? Again, not the OG owner (he has passed) so the seller won't know. I am planning on taking an OBD tester with, I know the codes to look for, but in case it's been cleared.

2.Suspension

Apparently, the air suspension is sound atm, but how would I test at the viewing besides lowering the car up and down I guess?

3. CAM Plug Oil Leak

I am taking a mechanic with me to do the inspection, so, we just remove these to see the 'seepage'?

4. VIM Actuator Cam Breakage

Absolutely not clue how we'd look for this? Rough idle?

5. Water leakage in cabin and engine bay

6. Electronics (especially seats and AC)


My question to you guys (a big one) are the ones above and what else am I missing? We live next a coast so will look for rust, but this car looks great and has less than 10,000 km per year (driven by a 70 year old, so, doubt it's been trashed).

I realize some of these might be incredibly dumb questions, but thank you for the help. Also, I am aware this is not a cheap vehicle to maintain, but I also only do 4,000 - 6,000 km per year at most (I work from home). That said, I am willing to keep up with extremely regular maintenance and treat the car well. I don't race, I don't trash, I love those things but I wouldn't do them myself.

Thank you all for your help
