XOM has been a very nice thing to have in my portfolio, I bought in mostly during 2002, for under $40/share.
I think its a bit too rich to buy now.
Probably is too high. I don't really follow it although I do have a few shares. Mine was a sentimental buy many, many years ago. When I was a kid my dad worked for a local Mobil delivery service for a short time in Michigan. I rode in the truck with him a couple of times.
