Interested in finding a great deal on a used Mazda RX8?

Are you considering purchasing a used sports car? Then the Mazda RX8 is a great decision. AutoUncle present 89 options, each one collected from an online marketplace or dealership website.

How much does a used Mazda RX8 go for?

A used Mazda RX8 costs between £1,795 for the cheapest variant and £4,995 for the most expensive model.

The used car price of an Mazda RX8 is determined by a number of factors, the most important of which are year, engine capacity and performance, the car's fuel consumption, number of miles not to mention trim level.

For example, a newer model with low mileage or a premium version equipped with a high-performance engine generally demands a higher price than an earlier version with less equipment and higher mileage.

What equipment levels can you get the Mazda RX8 with?

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 deals of cars with the same equipment variant and engine size. Otherwise, you might reach a wrong decision on which car to buy.

Is the Mazda RX8 available with multiple fuel options?

The Mazda RX8 exclusively uses petrol as its fuel. There are currently eighty-nine cars available at an average price of £2,785.

When thinking about which fuel type to buy, it's important to consider your driving habits. 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 short journeys, electric cars, plug-in hybrids or petrol cars are obvious choices. If you have a daily commute over longer distances, a modern electric car can be a great choice - especially if you have access to charging at home or at work. In a few cases with long journeys and limited charging infrastructure, diesel can be a practical solution. Bear in mind that diesel engines emitting high levels of pollution are not allowed in cities in a number of countries.

What body options does the Mazda RX8 have?

The Mazda RX8 is only offered in the hatchback body type in the UK. Hatchbacks seamlessly combine compact design with impressive driving dynamics and practical space. Their fuel efficiency and ease of parking make them a favourite choice for city dwellers.

Is the Mazda RX8 the best choice - or are there better alternatives?

The Mazda RX8 has various competing cars from the same segment.
