The only real difference with your interior are the front seats. Buying new is out of the question and finding a 4 gsr thats being broken will be nearly impossible. However those Recaros come standard in Lancia Integrales (EVO II's) Honda Integra Type R's and a few other cars. If you could get a pair cheap enough it would be no aggro to have them recovered to match your rear seats or go for a complete make over. You can buy the seats new still thr'u people like Demon Tweeks if you are desparate enough. Re-upholstering doesnt have to be expensive if you shop around. Theres a good place up near Northallerton (Yorkshire)
