yeah i noticed the same thing with that black r33 front seat at the factory, and when i questioned why it looked so bad they told me that the seat was bought from wreckers and was in bad condition and hence the loose fitting which made it look like vinyl...
the r33 rear seat that i saw and posted the pic of, the black with cream centre looks hott..thats the combo i am getting, if black looked shit i wouldnt go for it myself...
as long as you guys dont have seats that have collapsed somewhat you will be right with any colour..
