A lot of trucks and SUVs tout 4wd as a selling point, or these vehicles may come with all-wheel drive, which is different but similar in nature. While these may be great features for people who enjoy skiing, camping and long road trips through the mountains, many people never really put their 4wd vehicles to good use. People who live in the city do most of their driving to and from work, and 4wd is only ever really used on days with snowy commutes. However, so many businesses shut down on snowy days that even people who have the wheels never actually use them when commuting. Unless you plan on doing a lot of stuff outdoors, then I wouldn't recommend making 4wd too big of a priority when buying a new or used car. It's nice, but definitely something that can be lived without.
Why buy a vehicle without 4wd? Just because you want 4wd doesn't mean you have to get a giant truck or an SUV. This is a great feature to have, which can dramatically improve your safety during unexpected poor driving conditions. Often, having 4wd provides enough security to avoid having to carry tire chains and other devices in your vehicle. You can save a lot of money by buying a car or crossover that has 4wd, and not just limiting yourself to large trucks and SUVs. Dealers may try to sell you larger vehicles if you say 4wd is an important priority for you, but remember you can offset the cost of getting a 4wd vehicle by downsizing the size of the purchase you want to make.
