I was reading another posting and I noticed that TrailLeadr's Suburban has 207,000 miles. My '99 Suburban recently went over 100,000 and I'm wondering about tips on how to keep it going another 100,000. My old '86 Suburban started having problem after problem (transmission, steering, timing, rust, etc.) at around 150,000. We gave up on it. This time we started with the '99 new, so I'm hoping that we've only just begun.
