Is there a cheaper way to rent a car on a weekly basis?

I’m ready to join the green revolution by buying either an electric or hybrid vehicle. The Chevy Volt has my attention due to the low price, but I also don’t want to eat a ton of depreciation by buying a new one. How much does the Chevrolet Volt depreciate?

I just moved into this neighborhood and put in a really cool koi pond in the front yard. My next-door neighbor hates it and said they were going to enforce the CC&R, but I don't know how they can. Who enforces CC&Rs when there is no HOA?

I've owned my vehicle for eight years without having an accident, and I'm starting to think that I don't need collision insurance anymore. How long should I keep collision coverage—and if it doesn't seem to be useful, should I get rid of it?
