Reviewed a 2012 BMW 6 Series on Feb 13, 2025
The 2012 BMW six series grand coupe is remarkably an Exceptional, reliable one of a kind vehicle. I’ve owned two of them “650i Trim & 640i 4door”. Hands down, no complaints whatsoever during the time of which I owned/leased BMW model. Furthermore, the price point for its time in our era is impeccably underpriced in my opinion (used car/depreciated value per KBB to date). However, nevertheless, it’s good that it’s a hidden GEM that is slept on. Allowing the 2012 BMW to uphold its uniqueness and elite status quo, which I appreciate and value second to reliability, and this is coming from a man in my early mid 30s that has owned one of each model trim in the six series from 2012< it being my favorite car that I’ve ever “owned/leased/Pre-Own purchases”. Ref; BMW GrandCoupe’ 640i and 650i.

Awesome car, super fun to drive engine can be both pricey and problematic if your careful or unfamiliar with its common issues but if u can get past that the car is a BLAST to drive/own & turns heads everywhere.

Good looking, sexy, solid, but heavy. Handling isn't exactly what you'd expect from a car of the genre. My 2008 is the revised edition.. and does look much better than the first gen.. arguably better than even the latest gen....probably the best German car value out there right now. These cars go cheap.. and the are really great vehicles.

CarGurus recommends the 2015 BMW 6 Series
Summary
With 240 currently listed for sale and an average price of $16,776, 33.3% of 2015 BMW 6 Series listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2015 BMW 6 Series 5 / 5 stars.

Why it stands out
The 2015 BMW 6 Series stands out as a style-first luxury grand tourer that still puts driving enjoyment at the center of the experience. In BMW’s third-generation 6 Series lineup, it belongs to the era that added a four-door Gran Coupe to the coupe and convertible body styles, and it was also the generation that brought in the factory-tuned Alpina B6. That combination gives the car a broader personality than a simple two-door luxury coupe: it is meant to look dramatic, feel special, and deliver serious performance.
For 2015, the 6 Series also benefited from a visual refresh with new headlights and bumpers. The model’s appeal is reinforced by its strong equipment list and upscale cabin, along with the fact that BMW had already made it a comfortable and engaging car to drive. Buyers looking at this year get a car that is stylish and rewarding, but they should also keep in mind that the back seat is snug even in the Gran Coupe, and that ownership costs remain high. Owners’ enthusiasm for the car’s fun driving experience, luxurious feel, and strong performance lines up well with what makes the 2015 BMW 6 Series distinctive in the used-car market.
