No service required unless the engine is idling to slow and stalling at red lights. This maintence is only requied on a as needed basis. Idle speed should be 550 to 650 rpm.

If the vehicle fits your needs, and it still looks good 140,000 miles is only a number. If you love it, consider the 4000 an investment . A 2009 Escalade is surely going to cost a few bucks more :)). As far as what might break next, its a piece of machinery. Seems like you stay on top of things, As far as whether you should go to the dealer. It is electronically controlled. Bring to someone who knows what they are doing. The grief with a sub-par repair along with a large expense, is real tough to deal with. I say stick with the dealer. Good Warranty

Likely good. Belive it or not, the Escalade engines are bread to roar. Babying it all day isnt much good.

I advise
-new spark plugs (my personal fav is NGK Spark Plugs)
-Mobil 1 synthetic oil
-New spark plug wires
-New ignition coil
-New air filter (K&N)

The truck will likely improve.
