Should your next car be a used Mazda RX8?

Are you considering getting a pre-owned sports car? The Mazda RX8 is a great pick. In total, there are 85 used Mazda RX8s for sale on AutoUncle in the UK, each one sourced from an online marketplace or dealership website.

How much does a used Mazda RX8 go for?

The cheapest Mazda RX8 that is available here on AutoUncle costs £1,795, while the most expensive model is priced at £3,995.

The used car price of an Mazda RX8 is determined by a number of factors, the most important of which are manufacturing year, engine size and power, the car's fuel economy, how many miles the car has travelled together with the level of equipment in the car.

For example, a newer model with fewer miles recorded, or a more luxurious variant with a powerful engine, typically commands a higher price than, for example, an older car without special equipment and with many kilometres behind it.

What versions of the Mazda RX8 are available based on equipment?

The Mazda RX8 has an equipment variant called Mazda RX8 Evolve.

When evaluating the costs of pre-owned Mazda RX8, it is important only comparing the offers of cars with the same engine and trim level. Otherwise, you might make a wrong decision on which car to buy.

What fuel configurations can I choose from for the Mazda RX8?

The most popular fuel type for the Mazda RX8 is petrol.

Keep your driving habits in mind when choosing which fuel type to purchase. On a regular week, how far do you drive? Do you engage in many brief trips, or are your drives generally longer in distance?

If you drive mostly short distances, range is not crucial - so electric, plug-in or petrol are obvious choices. For daily long journeys, electric cars make the most sense if you can charge easily. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. Despite the rise of electric cars, diesel can still be useful for long journeys and lack of charging options. Note that there are countries where diesel engines with heavy emissions are forbidden from entering city areas.

The Mazda RX8 is only offered in the hatchback body type in the UK. Hatchbacks are compact cars that offer a great driving experience, not to mention the flexibility of ample space. They’re fuel efficient and easy to park, which makes them popular with people living in cities.
