The E23 7-series is already a bit special, for two main reasons. First, as I mentioned when I wrote up a 733i a couple of weeks ago, you don’t tend to see them on the roads anymore. Second, the beautiful design, which shares a number of features with the shark-nosed E24 6-series coupe, matches anything put out by Mercedes-Benz in the same era in terms of elegance and style. That is not something that could always be said about BMW products, even if they were more fun to drive than their counterparts from Stuttgart. But this E23 is even more special, since it’s a gray market 745i.  Not available in the US, this high-performance model represented the top of the E23 lineup in Europe and came with a turbocharged version of the 3.4 liter inline six cylinder M30 engine (here called the M106) and a host of luxurious and high-tech (for the time) accessories. Very few of these come onto the market, and rarely do they do so in the kind of condition shown here.
