Well, I'm right at 50k miles on my '06 MCSC, and the OBC has had me "come due" for exactly two scheduled services (oil change at 12,500 miles and "Inspection I" at 33,200 miles). The next service, another oil change, is looking like it's not going to come due until about 54,000 miles.

I got a free service agreement extension to 48 months/50k miles, and I'm really glad that I didn't pay for it, because both of the services I've gotten came due during the initial 36k service agreement period.

I've never gone more than 12 months between services, so I didn't qualify for any of the free annual oil changes, either.

At the rate I'm going, the fourth service ("Inspection II") probably won't come due until I'm past 75k, so even if I had extended the factory service agreement all the way to 75k miles, all I would have gotten out of it would have been the oil change at 54k. (Although I suppose it might have gotten me a brake fluid or coolant flush as well - do the dealers do those after three years or four years?)

I guess the point of my post is that if you're planning on doing a lot of interstate driving on your new MINI, think twice before paying for an extended service agreement, because you may not get very much out of it. Highway driving causes the OBC to *really* stretch out the service intervals, often to 20-22k miles or even longer.
