Advice for Purchasing: How Dependable are the High Mileage Older ML 350's

I'd like to buy a MB AWD SUV older with high mileage. It's what I can afford right now. I'm interested in the GLK 350 2010-2012 mostly, but I'm open to an ML 350 or at least a smaller six cylinder to save on gas (probably in the same year range). But I'm concerned about the frequency of repairs and costs of repairs if I buy a high mileage (100K+) older model. I know maintenance costs will be higher, which I'm fine with. And I know repair costs will be higher, but I'm most concerned about repair frequency. I only keep cars for 1 or 2 years while I save more and then sell them and upgrade. I've spoken to some people who have said that repairs are pricey but they only happen every few years. I want to get other peoples experience. How frequent were the repairs? If I only had one repair over the 2 year ownership period, I would be okay with that. I know owning a German made auto is going to cost more, I'm just wondering how much more in terms of repairs. I'm prepared to pay more in premium gas, maintenance, and insurance.
  1. What years are best for durability?
  2. What years have the most reliable engines/ transmissions?
  3. What years are worst for durability?
  4. What are the most common repairs for these cars and what did you pay for them?
  5. How frequent are repairs?
  6. What are the most important things to look for when doing pre-purchase inspections that could be very costly over the next 2 years?
I'll buy from a private party as I always do, with a thorough mechanic inspection, but I want to be fully aware of what issues I need to concern myself with and what I'd be going into (from a financial and resale aspect) if I buy one of these.

I'm also considering the 2013 BMW X3 i28 and Audi Q5 2.0 quattro. I've seen that year get top awards for dependability for older high mileage luxury SUV's, but the MB appeals to me much more. Please, any advice in making my purchase decision is so helpful.

My whole post just got deleted because he page refreshed. Basically, I was saying.....Don’t do it.
You have already described yourself as a Lexus person. Now you just need to save up a little bit more.

Ml350 with steel springs is as reliable as they come

Q5s are trouble. Youll go crazy with the sunroof rattle and it eats oil and isn't that fuel efficient.

X3 and Q5 are not comparable to the ML size and specifications wise.

What is your expectation for reliability?
Why a high mileage Mercedes?

For the same price, consider a Toyota 4Runner. One of the most reliable and capable vehicles built in the past 20 years.
