Within the city of Davis, bicycles are more than enough. However, if you have kids or plan to travel across the country a lot, than you might consider buying a car. The cars here are well maintained and even 10 years old car can sometimes look almost new. Cars can be bought from privet owners that advertise their used cars on [craigslist](https://sacramento.craigslist.org/search/cto), but a much simpler (and a bit more expensive) option would be to buy it from a car dealer. All you have to do is go to one of the local car dealerships, find a nice car, bargain for a good price, pay and go home with the car. The dealer will take car of all the DMV's bureaucracy. A list of Davis car dealerships can be found on [DavisWiki](https://localwiki.org/davis/Car_Dealerships) Another one that is not of the DavisWiki's list: [Sac River Auto](http://www.sacriverauto.net/)
