NA MX-5s are great in so many ways it's hard to count. In ability to hold cups? Eh.... If you have the stock cupholder that does okay, but it could be better. This cupholder easily presses into the front of your center console and is held securely in place with geometry (and is easy to remove). This is a much more convenient location than the stock cupholders, as it's not so close to the shifter, and is invisible when you're not using it (assuming you close your center console).
Fits both "normal" fast food cups and cans, and has a slot so longer things will still fit in your center console when you're not using the cupholder. This might work with some coffee cups, but they'd have to be pretty small diameter (this should fit up to 68mm / 2.7").
