So I'm about 1K miles away from hitting 100K miles. I bought my Jeep with 90K last March, and haven't really done anything mechanically except oil changes. It was bought new in 2005 by an older gentleman, and then owned by his sister, before being traded back in at the same dealership it was bought from (shop where I bought it). All I know is the service has always been done at this dealer, and from what I was told, it was well taken care of. I'm just curious what should be done, as far as plugs, fluids, etc., as I come up on 100K. I'm not very mechanically inclined, and live in an apartment with limited tools, so its hard for me to do much especially in the middle of winter. So I'll probably have my brother in law have the mechanics at his shop do most of the work when it goes in for an oil change in a few hundred miles. Any input is greatly appreciated. Thanks guys.
