Car valuations are estimates of how much a car is worth. There are several websites that offer car valuation services, including:

1. What Car?: This website offers a free car valuation tool that provides an accurate quote in seconds. Users simply need to enter their license plate number.

2. Edmunds: Edmunds offers a free appraisal tool that gives an accurate price for a vehicle in as little as a minute. Users can enter their VIN or license plate number and answer a few quick questions about the cars condition to receive a value based on recent data in their area.

3. Kelley Blue Book: Kelley Blue Book has been a trusted resource for used car values for over 90 years. They offer several valuation tools, including the Trade-In Range, which shows what a consumer can expect to receive for their car when trading it in at a dealer, and the Private Party Value, which reports on a fair price when selling the car to an individual instead of doing a dealer trade-in. Kelley Blue Books values are based on massive amounts of data, including actual sales transactions and auction prices, which are then analyzed and adjusted to account for seasonality and market trends.

4. Consumer Reports: Consumer Reports provides a car value estimator that uses Black Book trade-in value and market value to help users get the best price for their vehicle.

Car valuations are important for both buyers and sellers. Buyers can use them to ensure they are paying a fair price for a vehicle, while sellers can use them to determine a reasonable asking price. Its important to note that car values can depend on how the car is being sold. The Private Party Value is usually more than the Trade-In Value because if the car is sold privately, the seller is the one spending the money, time, and effort. Trading in at a dealer is convenient, but the seller may receive a little less.
