3.5L V6 life expectancy

I'm looking to get an Acura MDX, probably a 2001-2004. I'm trying to get an idea of how long I can expect this engine to go, i've noticed its in many Honda/Acura vehicles, so I'm assuming its a great engine. I've seen a few listed under $10,000 but already have over 130,000 miles, with the timing belt having been replaced already. Will it go well over 250,000 miles???

In my opinion, it all depends on the maintenance. I had a honda prelude 92 with 205k miles on it. and let me tell the engine was less noisy than my current 01 sentra. =) I'm thinking about getting a pilot. I'll try to get one with 80k-95k miles on it with a great maintenance record. Preferable 1 - 2 owners.
