Bay-Area Car Related Must See / Do's? Input Appreciated

[NvrDun71]

Was hoping I could get some input from local Bay Area/Cali members on some worthy car related stops I should make while I am in town next week? Long story short I will be in the area on my honeymoon and the future wife has given the ok for some car stops/detours since we will be doing alot of driving in and around San Francisco. Would hate to be in the area and miss out on a really cool shop, show, and or event only because I didn't do enough research in advance.

Any help or info is appreciated!
