Well, that's just odd. If I had any litter in my glasshouse, I'd spend the $7.99 for this in a flash! But I don't eat, drink, shop, run errands, chew gum, and often have no interactions involving little bits of trash when I'm out in Carmen the Cayman.Amazon says that won't fit a 718.
I will allow water bottles in the cup holders. I find that the smaller Fiji bottles work well. The newer bottles, while trying admirably to lower plastic usage, don't work. A refillable bottle designed for these cupholders would be awesome, dunno why that isn't a thing. If it is I would gladly buy it.
My personal policy is anything in the car must stay put at up to 1.2G or else it doesn't get in the car! This and anything you put in it will fail my policy...I'm thinking of getting some warning stickers "Must be 1.2G Tolerant to ride!Thermo Mug Porsche isothermal high gloss finish Capacity: 0.90 l Made of double-walled stainless steel Dishwasher safe Colour black Porsche WAP0500680M002selectionrs.com
I got one of these as a gift from a Porsche driving event a few months ago. "Porsche Thermo Mug XL". Holds 30oz of water and fits in my 718's cupholder. That said, fully loaded it definitely puts some load on the arm.
Porsche does offer smaller versions.
I used it on a 5-hour round trip drive a few weeks ago and it worked well. Not a canyon carve, though.
