I looked at various cupholders online for boats and marine applications, and they all seemed cheap and not terribly easy to use while driving. They required you to open the holder and manually flip up the part that grips the can or bottle. I wanted something that worked in one simple step.

I found what I was looking for online, and it turns out the cupholders I liked were out of a Mercedes SL-500 and other newer Mercedes models.

This wasn't one of the cheap looking plastic holders I had seen elsewhere, and the price didn't reflect this either. Compared to other holders, this was 5 or 6 times the price.

Once they arrived, I was surprised to see that they were a little wider than I had expected (over 1 inch wide when closed). I also was having a hard time finding where to mount them. Other aftermarket holders for the DeLorean are commonly made to hang off of the passenger side of the center console. I held one of mine up to see how it would look there, and I wasn't happy. There was no way to make it hang down straight without making a bracket, and I wasn't willing to clutter up the console with them.

I held one up to the doorsill, and I was very happy with how it looked. I decided this was where I would install the cupholders. Drinks would be within easy reach, and when not used, the cupholders wouldn't stand out too much.

First I had to dismantle them to drill them into the fiberglass. These are put together so well, getting the ABS plastic pieces apart was a little tough. Time and patience got the job done.

I was a little worried about drilling the rear of the holder into the fiberglass crooked, but it turned out great once I got all 4 screws in.

From here, it was time to put the cupholder back together.

Now it was time to test the function of the unit.

It closed easily and looked great.

And the final test: A bottle of Propel

A view from the passenger's perspective:

The passenger side of the car has one in the same exact location as well.

Let me know what you think!
