Hi everyone
I'm going to buy a ML320 2000y with aprox 60000m on it. It's my first Mercedes and it's used so I need an advice. What I have to check first? What possible problems I could get in future?
Thanks in advance

Have a pre-purchase inspection done by a MB shop OR dealer FIRST!

First of all, make sure the check engine light comes on when you turn the key to run, position 3. This would detect the PO disabling the light. Of course, if the check engine light is lit with the engine running, you will want to take it somewhere that reads the codes for free, Autozone, Checker, etc.

The 5 speed automatic is about $5000 to replace new! No dipstick was factory installed so figure some way to suck out a little fluid for a visual inspection. The transfer cases were problematic in that the electric shift motor fails. Make sure 4WD works. You can only engage with the trans in neutral and the vehicle stationary. Engine speed will markedly increase in all gears with the 2.3 to 1 gear reduction

Make sure all the power door locks and power windows work. Test that all keys provided will start the engine (and keep it running)

If it has Arvin shocks (OEM), plan on replacing them, preferably with Bilsteins.
They will be dead! $750 +- 250

A recall on the catalytic converters may include this vehicle. They are having cracking problems so check exhaust for soot stains, etc. About $3000 a set!
recall would be free, welding would be much cheaper if you have to pay.

The fuel level gauge is prone to failure and will not display full when the tank is filled. Just a nuisance!

Still a great ride, my wife prefers ours to the Eldorado! Just get the best price you can.

Ask to see if the following has been changed...

1) center panel window switch?
2) power steering hose clamp (see if recall done)?
3) shocks replaced?
4) Center drive shaft bearing?
5) Aux fan harness upgrade?

These are pretty much the things that will break eventually... mostly at around 90k miles... well, at least on my 2000 ML430...
#1 ~ 75k, #2 ~ 65k, #3 ~ 100k, #4 ~ 95k, #5 ~ replaced myself ~ 60k.

I think the engine and the trans is kinda hard to test... but for the engine, maybe you can pull the dipstick and smell and look at the oil... see if they are really black, any residues, and smell burnt... if smell burnt, maybe worn piston rings; if black, may need oil change; if residue, worn engine...

Hope this helps...
