Besides Ebay, does anyone know where I can find OEM 16" 6 spoke Toyota Sequoia wheels at a reasonable price?

You might take a look at either of these places:

www.wheels-and-rims.com
www.tirerack.com

If you live in a metro area served by craigslist.org, it might be worth a shot. It's also possible that some of the larger tire stores in your area may have some take-offs.

I just sold my Tacoma wheels using craigslist - there are a lot of them out there. Good luck!

Take care,
