Add me to the list. I bought this 2004 white 6sp a couple years ago for my gf with 104000 on it. Maybe paid a bit too much (14000) but we do love it. It now has 122000 miles. Since we bought it I've found some issues with it:
- secondary air pump failure (cel)- not worried about it
- burns lots of oil. Thinking this is from the ccv being bad. I was going to replace it but then found out how much work it is and decided to delete it and install a catch can. Also the hose from the crankcase is broken so I think I'm loosing vacuum which could be a cause for burning oil. Sound right?
- clips for the door weather stripping broken. Haven't found a source for these.
- deleted the cdv about a year ago and that made shifting soo much better
- sometimes on a very cold morning it idles rough and dies. I'm thinking this might have to do with my ccv issues. Condensation freezing on the maf maybe?
- intermittent wiper function doesn't seem to work properly

Other than all that everything else works great. The super low first gear is annoying though and I've been trying to figure out a solution. I've read this whole thread and I've gathered that I could swap my diffs to get higher gearing but what about just getting taller tires? I just bought some 18" rims for it and was thinking of putting 265/60r18 on it which would be 1.5" taller and almost an inch wider. Seems like this would be a easier/cheaper solution than swapping out diffs to me,no? I would like a bit more rubber on the road anyway. And it might make the odometer more accurate. Usually a car's odo will read a bit faster than reality. Has anyone tried this? I'm suspecting Happy with the supercharger has taller tires and that's why he doesn't mind the low 1st. Or has any one figured out if you can easily install a x3 or a 530xi 6sp in it to get normal ratios? Thanks for everybody's input and very appreciative to have this resource.
