After my problems with securing an ECU programming update through Don Rosen (described elsewhere in this forum), I made an appointment with Rich at Princeton MINI. While there's no way to know, as of this writing, if the ECU update has cleared the cold start problem (the car's still hot from a 50 mile drive, after all), almost everything else went well. I was met at the service entrance (signs at the entrance to the dealership lot helped me find where to go) by a valet who directed me to the service desk. Rich remembered my call and appointment, wrote up the ECU warranty work and had no problem adding ICE option programming and an oil change to the work order. He had a printed list of ICE options and said "check what you want". The work was finished up in a reasonable amount of time (90 minutes with 30-45 minutes budgeted for the ECU work). The sole wrinkle in the visit showed up at the end. It took about 30 minutes to get the car back after the bill was closed. As best I can tell, the car wash was backed up (Good News: Princeton washes the car inside and out - Bad News: it's been pouring rain all day - didn't much matter about the exterior although I was happy to see the inside cleaned up) and then my car was "lost" - confused with another Chili Red / White
MCS. Nonetheless, at least people were willing to talk to me and tell me what was going on.
How does this experience compare with my experience with Don Rosen? The service writer at Princeton was polite and personable while the Don Rosen service writer was rude. Princeton was ready to do the requested work and had no problem accepting added work while Don Rosen couldn't do work requested when making the service appointment. I was charged .5 hr of labor for the ICE programming while the Don Rosen technician told me "tell me what you want and I'll do it on the next visit." Princeton definitely fumbled the ball on returning my car although they did wash it while Don Rosen got the car back sooner after the work (sic) was done but it wasn't washed (they had a sign saying they were not washing cars because of the ongoing draught in this area). Finally, the drive time to Princeton MINI is approximately the same as that to Don Rosen even though Princeton MINI is twice as far - one's a city drive and the other uses the Interstates.
Bottom line: I'll stick with Princeton MINI.
