There's a difference. If you want top notch quality, go importsextreme, otherwise a great 2nd(and one I went with) is interior-innovations. I called 6 places throughout the seattle/eastside area and they all gave me pricing. I chose to go with Hoglunds in Everett for 2 reasons. 1: They're near me... and 2: They specialize in hotrods and a lot of classics and have been doing this for YEARS. That kind of attention to detail and skill is what sold me on them. I bought the full leather interior innovations kit and had them do the install. Was about $600 to install. You may be looking at a little more given that I was the first 300ZX they'd ever done and underbid the amount of time it would take. I also had minor fixes that needed to be done.
