The N74B66TU only needs ~11 pounds of boost to make it's power, so it it doesn't work very hard. There are really no "common" problems with these engines like you find with the higher boosted hot-V's. N74B68 version of this engine is used in the Rolls Royce lineup.
I did lot of research and was planning to get an M5, but you can get a M760i for the same money. I drove both. The M760i is pretty close to the M5 on "fun to drive" (no track use) but way more enjoyable to drive when you aren't having fun. 590 ft/lb that comes in at 1550 RPM that lasts all the way to it's 7000 RPM redline is a big part of it's charm, it has almost no lag and is always willing to faster then you need it to. I already have a "track" car, so the M5 offered nothing I wanted that the M760i couldn't do better.
My guess/hope, it will hold up better than an M5 too. There were a few I found while shopping with over 100K miles for sale, they seemed to hold up very well. If so, I may end up keeping it well after I retire.

Good to know. I am not looking for a full blown M car either, since I already have a track car, and an MXXX can is plenty enough for a long term car.
