Ok, I've got one with about 125k on the clock. Last winter was winter, so I did not drive it but twice from Oct - December of 2009. Since then it has developed a fuel line leak as noted up under the IM, sometime while sitting. So I have driven it...... What 3 times this year? Might soon become daily driver...

1. Beg for forgiveness, how could I let it sit for months on end????
2. I'm going to be diving in soon, taking off IM, replace a couple of fuel lines I could not get to w/o taking off the IM. Replace o-rings with viton.
3. Seems like I will need to replace some clips, so I will do that.
4. Probably has original belt on it and I have a new belt tensioner.
5. Will change the oil and fuel filters as well as air while I am at it.
6. Oh, it is dusty and I have not washed it this year.
7. Probably replace battery, it is now weak.
8. Due for tranny fluid and filter change - O'rings and a magnet if I recall correctly should be added?
9. Anti-freeze is probably 3 yrs old
10. PS fluid change?
11. brake fluid change?

What else should I be pondering while I am in there?

Rumor at work they may pull the company cars, so I might be forced to drive this daily at least 150 miles.

Looks like you have it pretty well covered. Only things you might add:

Change diff. oil
repack wheel bearings
Check motor mounts (they are about due)
be sure to use proper tranny fluid, the MB stuff.
Clean the MAF and EGR, they like to get dirty and send DTC's to your dash display

That's all I can think of since you did/are doing the plastic fuel lines. Oh, don't forget the O ring behind the SOV and the one on the pre filter (funky size, be sure to get the right one).

You'll like driving the car, I love mine.

Be nice to drive it again, it spoils me!

Also have done the A-arm bushings, which was not bad at all.

Now I just need time and some $ to get it done.

If you take out the winshield washer bottle and fuel filter housing, you can get at ALL the fuel lines very easily
