The BMW M6 is quickly becoming the M bargain of the 1980s, replacing the M5 as the go-to Motorsports product from the company. There’s some irony in that, considering that in the period it was the premier product from Munich and until quite recently was considered the most valuable. However, as the M3 prices have soared and recognition that finding a clean E28 M5 is becoming quite difficult, the slightly more plentiful M6 is suddenly a more reasonable proposition. That said, prices on M6s are all over the map – from the low teens to well over the $30,000 mark. Today I have two similar looking 1987 models to look at; I usually focus on the updated and better looking (in my opinion) ’88s, so this is a slight departure for me. Besides the shining exteriors, where does the difference in these two models lie and are the asking prices in line?
