The used car valuation company predict the four-door, four seat coupe, which debuted in 2003, will still retain almost 40% of new retail price - £21,150 for the 190bhp model and £22,650 for the 229bhp derivative at three-years/60,000 miles - while early models now reaching used car forecourts are retailing at £10,150 upwards.
Jeff Knight, forecast manager for CAP, said: "The RX-8 continues to have driver appeal. Although it has been on the roads for four years the car continues to have a ‘wow’ factor as it looks good and is completely different in styling from any other model."
The used sticker price on an 03-plated 190bhp with 60,000 miles on the clock continues to be over £10,000, according to CAP, while a 53 model at similar mileage will retail at around £10,395. Move up to the 229bhp and an 03 model will cost around £11,250 at 60,000 miles with a 53 version costing around £11,495.
Simon Harris, consumer editor at car buying guide Parker’s said: "Used car buyers are attracted by the RX-8’s status as a stylish sports coupé with room for four adults plus luggage. It isn’t merely a coupe version of a less exciting upper-medium saloon – it has proper sportscar styling and handling, and is very well equipped."
