There are five main factors that have an impact on what a pre-owned Subaru WRX STI might cost: the year, engine size and performance, the car's fuel economy, how many miles the car has travelled as well as the equipment level of the car.

There are a few questions you should ask yourself when deciding on a fuel type. Is your car mainly for commuting, or do you tend to take it on long road trips? On average, how many miles do you drive per week?

For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work.
