You can navigate the website, just a bit sluggish.
Wow! I just did a right-click and looked at the source.
The home page itself has over 5,000 lines of script and some of those lines are immense, the other pages are bigger. The performance of this site will depend more on your processor power than the speed of your internet connection. It's not too bad on my laptop but I wouldn't try it out on a phone.
I like the car though!
