I suggest checking out copart.com. From experience i have found it sometimes cheaper to purchase a whole (unusable) car and just take the parts you need. I saw a few 88 benz's listed that have the center console still in tack (not tan interior though). Keep checking because they have thousands of auctions daily, I've had good success from the site.
