I found this interesting Signal Green M4 on a Porsche forum which is fitting since this bright green was offered on the 997 GT3 RS.
Signal Green is a bright and bold color and I think it looks really good against the aggressive front bumper and black accents of this BMW. Specially ordered through BMW’s Individual program, this color is quite rare and dealer believes only a few M4’s have left the factory in this exterior.
The M4 is outfitted with a 3.0L turbocharged inline-6 that makes 425hp and 406 lb-ft of torque and can complete 0-60mph in 4.1 seconds when optioned with the 6-speed manual transmission. This new F82 chassis has more power and lighter than the previous E92 due to more aluminum body parts and a trunk lid that is made of carbon fiber.
The exterior looks similar to the E92 but freshened up with a really nice front bumper and LED headlights. Like the previous generation, the roof is made from carbon fiber for weight savings and this car has been optioned with the M Performance exhaust and titanium exhaust tips which add a eye-watering $5,500 onto the price. The individual exterior paint was also another $5k option.
The interior is full Merino leather and the front seats have a nice design to them with grey stitching adding contrast to the black leather.
This individual M4 is new and the dealer is asking MSRP $88,235 which seems fair for such a unique car. If you’re interested its located at Sewickley BMW in Pittsburgh PA.
