Well its been a while since I've been on, but the speedometer on my 1984 BMW 533i was broken so it was kinda hard to update a mileage log - and now it's been retired @ 462,000 miles. Anyway got a new car, it a 1997 BMW Z3 1.9 (with working speedometer) and a new milage log. I wasnt sure what to expect for hm potential, but the first 2 tanks are looking good. I've gotten all the service caught up and maintinence done - and changed the OMG 4.44:1 differential to a 3.25:1. I'm welcoming any questions/suggestions on this one. It's the 4 cyl with 4 spd automatic, my commute is approx 40 miles each way in mixed suburban driving.
