A 2016 BMW M4 GTS with 895 miles on its odometer is sitting on Bring a Trailer right now with a bid of $100,000 and five days left on the clock. That number already tells you something about where the collector car market thinks this thing belongs.
The M4 GTS was BMW M’s track-day special, one of roughly 800 built worldwide with only about 300 allocated to American buyers. Its party trick was a water-injection system lifted from BMW’s motorsport program, bolted onto the S55 twin-turbo inline-six to squeeze 493 horsepower and 443 lb-ft out of 3.0 liters. That’s 68 hp over a standard M4, sent to the rear wheels through a seven-speed dual-clutch gearbox with an M Driver’s Package that raised the electronic limiter to 189 mph.
This car wears Frozen Dark Gray Metallic with the signature Acid Orange roll bar and 20-inch Style 666M wheels. It’s the look most people picture when they think GTS. The seller disclosed paintless dent removal on the front bumper cover, and the Michelin tires still carry 2016 date codes, which tells you everything about how much this car has actually been used.
Inside, the rear seats are gone, replaced by that Acid Orange four-point roll bar. Lightweight M sport seats in black leather and Alcantara face an interior that still has cruise control, climate control, head-up display, and iDrive navigation. BMW didn’t strip this car down to a race car. They stripped it down to something that looked like a race car while retaining enough civility to drive to dinner.

Carbon-ceramic brakes behind gold calipers, three-way adjustable coilover suspension, a carbon-fiber roof, adjustable rear wing, and a titanium exhaust were all standard GTS equipment. This wasn’t an options game. You got the car BMW M wanted to build, and you paid $134,200 for the privilege.
That original sticker price matters because recent Bring a Trailer results for higher-mileage GTS examples in similar colors have landed in the $70,000 to $75,000 range. The market spent years punishing these cars after their initial speculative frenzy cooled. Owners who bought at peak in 2017 and 2018 watched their investments sink by nearly half.
Now here’s a GTS that’s a museum piece, barely driven, original window sticker included, clean New York title, and it’s already commanding a $25,000 to $30,000 premium over driven examples. The question is whether five more days of bidding push it toward that original $134,200 number or whether the market decides 895 miles and a decade of garage time don’t add up to new-car money for a car that’s nine years old on paper.
The water-injection system was clever engineering, but it was also a maintenance question mark that BMW never carried forward into later M cars. The tires need replacing before anyone turns a wheel in anger. And carbon-ceramic brakes that have sat largely unused for nearly a decade aren’t exactly confidence-inspiring without a thorough inspection.
Collectors are betting this is the floor for low-mileage GTS values. The bidding will answer whether they’re right or whether the broader M car market still has room to fall.
