Mazda RX-7 Series 1-5
This year marks 40 years since the first RX7 was released and what a difference it made to the sporty coupe market. To begin with it made Mazda a contender for international motor-sport glory and provided a platform to have a go at Porsche in road-car sales. That intent can be clearly seen in the shape and configuration of Series 4 and 5 RX7s, especially the turbo-engined cars. These when new and today cost a lot less than Porsche’s 944 Turbo and less to run as well. Demand for really good Series 1-3 cars and especially the later Limited versions are pushing average values of pre-1986 RX-7s past $20,000 and occasionally to $40,000.
