Oooh. More than I'd be willing to pay though. I picked up my tan leather seats, rear door cards, spare set of headlights, OEM underseat subwoofer, leather steering wheel, fog light grilles, and floormats for $300 from someone parting a car out on craigslist.
You're not too far away from me, might be nice to see what you find. I still need new bits like a front bumper skin, rear cup holder (tan interior), glove box surround, and maybe a new grille. Not a fan of leather though.
I'd love to swap out mine, but...
1) to look right, you'd have to gut the entire interior including the dash.
2) I'd most likely lose the rear armrest, since I believe it only came with the LL Bean and VDC - neither of which came with black leather.
