new Dodge Durango (...) Is it a best car to keep for a long time

Obviously not, this is far from being "the best car to keep for a long time".

The platform it's sitting in was completed in 2006, before Chrysler and Mercedes have separated.

This is just a 2000s Mercedes with a Chrysler powertrain...

Also chances are that it will soon be discontinued, as has its sister car - the Grand Cherokee.

I do not think this is a good option, typical Daimler-Chrysler crap.

I heard scotty mention (...) that he will plan to get a new Dodge Durango

Obviously not.

Scotty did say that if his car will get wrecked at some time down the line,

That he would consider a Corolla Hatchback manual 2.0L.

(But even there, most likely not new)

Or rather get a new Mitsubishi outlander

Realize that Mitsubishi was bought by Renualt-Nissan.

The Outlander is nothing more than a Nissan Rouge.

Both based on the French Renualt Megane... nothing Japanese about that "Mitsubishi".

low budget for a three-row midsize car?

I'd wait to see if the new Honda Pilot is any good.

The 10 speed automatic seems promising so far.

I can't think of a good low budget 7 seater and most of those did not sell on the US market.

US 3 row cars tend to be based on trucks or big sedans - and not inexpensive economy cars / sedans / commercial cars.

Scotty doesn't buy any new car regardless of the manufacturer.

Is it a best car to keep for a long time unless you know how to maintain them yourself?

What engine are buying with? Pentastar V6 or HEMI V8? The ZF 8-speed transmission is good.

Pass on that.
