Brother, if you can do that stuff you can do a valve adjustment on an oilhead. It's dead simple.
Here's the deal on your original question. BMWs quality assurance program is crap. You either get a good one or a bad one. If you get a good one, it will run for hundreds of thousands of miles with very little maintenance. Literally. If you get a bad one it will cost you multi-thousands of dollars in repairs every 30K miles. Literally.
With that in mind, I'd trust a high-mile bike more than I would trust a low-mile bike. A bike with 75k miles can be had pretty cheap, and will probably run another 100K. A bike with 10K miles will be more expensive and can have several multi-thousand dollar time bombs ticking.
