We rented 2 GoCars for some friends that came into town. It was actually a lot of fun and despite some of the negative reviews about breaking down, thank goodness we didn't. I was also concerned with how big the GoCar was. One of the guys is a tall 6'3 but he fit perfectly. Any taller may have been uncomfortable. Parking was still a pain but probably could fit 3 in one space, tightly. The parking garage charged us motorcycle rate which was nice, but you may want to mention it. We zipped all over San Fran and we loved the GPS/tour guide. Some good information historically. The GoCar was easy to get adjusted. I can't even tell you how many pictures were taking pictures of us, we made sure to pose. haha! It was a lot of fun. We rented for 3 hours and it was perfect. We also rented on a Monday and thought traffic would be less which it probably was but not from the Ferry Building down to the Wharf...if you can avoid it, I would. It's a lot of bus exhaust. Overall, it was an awesome adventure and very happy we did. I also suggest upgrading to the higher power cars. Climbing those San Fran hills...the extra $15 was totally worth it!
