Frequently Asked Questions

How fast do cars depreciate?

A new car loses about 20% of its value in the first year, 15% in year two, and 10-12% per year after that. On average, a car is worth about 40% of its original price after 5 years. Buying a 2-3 year old car avoids the steepest depreciation.

What cars depreciate the fastest?

Luxury sedans, electric vehicles with older battery technology, and large SUVs tend to depreciate fastest, losing 50-70% of their value in 5 years. Brands like BMW, Mercedes, Jaguar, and Maserati often have the highest depreciation.

How do I calculate my car's MPG?

Fill your tank, reset your trip odometer, and drive normally. At your next fill-up, divide the miles driven by the gallons needed to refill. For example, 300 miles driven on 12 gallons equals 25 MPG.

What is good gas mileage?

Good gas mileage varies by vehicle type. Compact cars should get 30-40 MPG, midsize sedans 25-35 MPG, SUVs 20-30 MPG, and trucks 15-25 MPG. Hybrids typically achieve 40-60 MPG in combined driving.
