Complete the meta description. Get an H1 tag on there that relates to the theme of the homepage. 486 links on the homepage! Yikes. Instead of putting all of those links on the homepage, link to the different categories where you can then include more links.

Also, I highly recommend the Copy Hackers books. Your main headline is too wordy and falls into the telling not showing. Learn How To Fix Any Car is an alternative option that would communicate the same message.
