BMW
US-based BMW enthusiasts may remember a special edition model called the Lime Rock Park Edition, released in 2012 for the E92 M3 Coupe. Named after a racetrack in Connecticut, this model borrowed the Fire Orange paint scheme from Europe's M3 GTS tied to the lesser Competition Package. BMW only built 200 Lime Rock Park Editions, and today they command a hefty premium over a standard E92 M3, especially the manual transmission ones.
If BMW did build a Rockingham Edition M3 or M4, we'd like to see Fire Orange brought back as the paint color, though one of the automaker's other Individual colors would do nicely as well. The Lime Rock Park Edition had other unique touches, too, including a titanium exhaust muffler, carbon fiber exterior pieces, a numbered plaque, and a decal showing the track in the window. All of these seem like simple additions for BMW to make on a new special edition model.
