There's a huge downside to the Frunk in the Model S. In order to make something that was completely unnecessary (given the large size of the rear trunk) Tesla designers packed a whole lot of mechanical components way down low in the front of the car. I made the mistake of running the nose of the car over a short parking curb, heard a scrape and didn't give it much notice, as on other cars it might scratch the underside of the bumper cover, that's all.
The Tesla with the Frunk? I was stunned when I got out of the car and saw all kinds of stuff hanging. I took it to an approved Tesla bodyshop and the owner simply looked at it and said "$6,000, and I already know all the parts damaged". I asked how he knew and he responded "We see this all the time". The insurance adjuster approved the repairs and the body shop sent Tesla a manifest of all the parts needed. I was warned that it'd take a couple of weeks for the parts to arrive, as Tesla was notoriously slow.
10 weeks later, most of the parts arrived. What didn't arrive they scavenged off other brand new Tesla that were there for repairs prior to delivery, knowing that when my remaining parts arrived, they'd be installed back into the donor cars. The repairs took another 2 weeks
If the Frunk wasn't there, and all that stuff was located up out of harms way, I and all the other people who had this problem wouldn't have gotten burned. So, I'd recommend 2 things. First, don't get googly eyed over the coolness of the Frunk. Second, keep a very safe distance from any parking curbs, else you will be without your car for 3 months, mostly waiting for parts.
