How many miles on a 2007 is too many?

So looking at some high mile 2007 JKU's. All look to be ok and one owner. Can do my own work so the miles dont make much of a problem. But when is it too high?

I have heard of the 3.8 engine supposedly going 200k miles but I only know of one personally at just over 100k miles and it is a 2008. There are a few members on the forums that well into the low to mid 100k range.

Personally, I feel it is not different than any other engine/transmission combo, it boils down to how it was driven and maintained. I keep very detailed records on all of my vehicles but I know that is a thing of the past anymore.

If you could find one that the owner had all the maintenance records and could show its history, that personally would set my mind at ease a little.

I put 140k on a 3.8 in a Grand Caravan and it ran like new when I sold it.

On a Jeep one mile is too many and a million not enough.

I have a 2007 JKU with 140K miles and the engine has had no issues. My mechanic says that he has one in his chrysler (not sure what model) and that it will easily last north of 200K.
