i just fitted a Nardi deep corn steering wheel on my car, has that deep look and red stitching. Make sure BEFORE u take your steering wheel off to disconnect the battery, if u dont the air bag light will come on and stay on until u visit nissan and get them to turn it off (or just remove the globe)
what ever you do dont drop the steering wheel as the air bag might come out, and they cost........7k to replace
Also in some cases if the air bag comes out in a small crash most insurance companies will write the car off as u need a new dash, and airbag.
