I have a 1995 850 turbo which just passed 120k miles. So far, overall I have 22.3 mpg (60% city driving in Chicago), typical overall 27-29 mpg in long trips (e.g., to Boston in December, to the Rockies in the summer) with full load and average speed on highways of about 80 mph (with occasional excursions in the 130s even at altitudes above 8,000 feet), perhaps 1/4 of a quart oil consumed during the first 120k, and overall have been very happy with it so far. Major jobs (that I recall) so far have been A/C evaporator at ~ 52k, oxygen sensors at ~100k, and 2 50/16 tires and one wheel at 30k. Currently, the only item that does not works all the time is the horn system (any ideas? it works about 70% of the time; the horns themselves are fine).
Based on what I read on this web site, have I been very lucky with my car? What (major repairs) should I expect from now on? Naturally, oil changes every 3k, air filter every 30k, spark plugs every 30k, timing belt every 70k, and tires every 55k. Two items that may have helped my car: (i) to change to 55/16s from 50/16s (with excellent grip in any type of weather ever since and no loss of any more tires or wheels), and (ii) to be gentle with the turbo after hard driving. Any other tips, please?
