A lot of dealers will offer a leather package if you ask for it...but like everything at the dealership...you're going to pay. 2007 WRX Limited came with leather. Leather lost its charm to me along time ago, hot in the summer, cold in the winter, and you slide all over
Aftermarket leather is usually cheaper and higher quality than factory leather (unless you're talking about suede interiors in top end Mercedes or something like that). Plus you have a ton of lattitude to customize it how you like. That said, check out the stock interior in the 08's, I really like it.
