Willie aside, I voted stainless. Years ago before the dawn of cupholders most autoparts places sold a holder that hung on the door. I wonder if any of these are still around.

I usually don't have any drinks in my vette just for simple reason there is no place to set it when you are not drinking it. I voted for the stainless one. It would be a good one to have at work.

I bought one of those litle cup holders that fit over the brake handle...   STAINLESS would look real good in it!

I've been thinking of buying one of those...Would you recommend it ?? 

Yea, I was thing of getting one of those brake cup holders too...pricey,
but my willie is woth it. Also, I vote Stainless, though I would also like to
see a ceramic "traditional" coffe mug for the home/ weekend slurper as
well.

what they said!!!!!!!!    

    

I got one of those cup holders too, and it works pretty good. Only problem I have is it's a bit too tight on the brake lever so I will have to modify it. It's too hard to get on & off. Of course you don't want it sliding around either. Also with a 4 spd, it is a bit in the way of shifting. I use it mainly on the long run and it works great.

the stainless steel for sure, if my coffee gets cold I can always put the cup on the side pipes to warm it back up

Stainless, as due to the heat coming through the firewall, the plastic would probably melt.  If I could keep the temperature constant, I could probably bake cakes as well.

I agree with Adams' Apple, I ain't got no stinking cup holders, but I sure do drink a lot of "Beverages" in the garage!  Think the stainless will keep stuff cold too!
