The "About" text for your car is making the rest of the page boldface and italisized. This is part of the problem. The other half of the problem is Internet Explorer.
You'll need to edit the information for you car. On your garage page, click the pencil icon in the lower left corner of your car's picture.
In the "About" box, you'll probably see a piece of text: [ b]
(I need to put a space after the "[" or the forum will make my text bold too).
There should be a matching [ /b].
Same goes for the italic tags. If the bulletin board tags aren't properly opened and closed ([ b] opens and [ /b] closes), then it creates bad code on the web page itself, which causes Internet Explorer to throw an error.
[ b] Bold face text [ /b]
[ i] Italisized text [ /i]
(Again, I put a space after the [ character so the forum doesn't see it as bulletin board code.)
All other browsers don't suffer from the same problem. If you have any more questions, just reply back. If you want, we can fix the code in the About text for your car.
