I'm curious what the general consensus is on what the approximate mileage lifespan of a C320 4Matic would be.

I'm only at 73K miles now and was thinking about giving my car to my mother next year to replace her 1999 Buick Park Ave - but I don't want to do it if the car really only has 190k miles of life.

190 - 73 = 117. Why is that not worth it?

If she babies it, it should easily get to 200. And if she doesn't, it was free for whatever timeframe she used it. It's a win-win, especially as an upgrade from a Park Avenue, unless she likes the size of that thing.

I'm used to project car hell. Before the Saab, I had a '75 Porsche 914 and an '85 Jaguar XJ6 that I bought, worked on, sunk a lot of cash into, etc with very little payout. I just wouldn't want to turn a car over to my mom that would turn into a money pit.

She likes the 'Park because it "holds the road", which the 4Matic does very well, despite being a smaller car.

But like I said, I just wouldn't want to turn something over to her that would be a money pit.

well my 01 c320 has 152k on it and really besides maintenance has been very cheap to own. I have not had any issues since my warranty ran out at 100k i am replacing the worn shocks but i consider that maintenance so that is really it.

She thinks a Park Avenue holds the road?!

190k miles of life isn't good? I would not keep a car for so long ever. I wont even make 2years with my C280.

Our 200k mile Camry was one of the most special cars ever. Maybe it's just me but once a car has a lot of years and miles with me it seems a lot more special than it started out as.

+1 every one looks at my car and goes wow nice car or look at the spoiled brat lol. And i chuckle to myself that it has 152k on it and people still go wow.
Every time drive my car i think wow this car is awesome even when loaded down with crap like it is know (i am moving like 1 mile away from my current house so it is the designated moving c320 lol)

The V6 models will go 500,000 miles with ease.

with proper maintenance and care, these cars should last a VERY long time.

She is a "mom". She calls me when "the internet goes down". Her line of thinking is that the heavier the car is, the more it "holds the road" - transmission, tires, and other suspension components never play into the equation.

Awesome
