You guys need to stop comparing airheads to bricks to boxers. Used bricks sell for well below their intrinsic value. Always have. Nobody wants them. Used airheads, on the other hand, sell for well above their intrinsic value, and appreciate in value year after year. Always have. Everybody wants them. Used oilhead boxers sell for about the miles left in them. People want them, but they are not yet collectable.
The R65 is a perfect example of an airhead worth more than its value. You'd be hard pressed to find a decent R65 selling for less than it cost new. Even more true for this rare LS model.
So the question becomes, what do you want to do with it? Do you want to collect it, flip it, or ride it? If you want to collect it, you could shine this one up with some TLC, admire it parked in the garage, and watch the value climb. If you want to flip it, you'd need to score one needing more work than this, so that you could add value. If you want to ride it, just be aware that BMW didn't wring anywhere near as much power per cc out of an airhead boxer back then as they do out of an oilhead boxer today. Also note that the LS is the least distance ride-able R65 made. Most of your R65s come with side bags and racks. Many an R65 owner will wax enthusistic about the week he spent carving the Blue Ridge Parkway. Not on an LS. Strictly a weekend afternoon warrior. If you want to ride an airhead on the twisties and be back in time for dinner, this is the model. Lighter and sportier than the raft of R100RTs still on the road. You won't lose a dime on it.
But if, as you say, what you want is to try a boxer, then go look at the slew of R1100Rs and such that you can pick up for less than this. They have tons more power, you don't over-pay, and they have progressed beyond the Rube Goldberg arrangement of leaky push rod tubes and 14 clamp fuel connections and oddball air tube elbows that plague the airheads.
