Available at Target, Amazon, etc. It's small enough to fit snugly and reach the bottom of the cup holder. Not cheap with street prices between 20 and 30 dollars depending on color and location, but over 1100 reviews at amazon and a 4.5 star rating suggest it's a solid mug to have even without the tiny cup holders.

...

The (arguably) more attractive vacuum insulated travel tumbler (shown below) with the smooth curved sides is, unfortunately, a little too big. It leaves about 3/8 of an inch below it before it jams into the cup holder. That means a top-heavy full cup of coffee ends up on your floor. Not good even if the mug claims to be spill proof.


Happy motoring.

 

I scored one of these today at the red bullseye, and I confirm it works great in the CM. Good call!

 

I've had one of these for a few years. It's a great mug and can take a lot of abuse. Coffee stays hot for hours and it fits in the cupholders. What else could you ask for?
