OEM Toyota 5x100 16x6.5 - $150 (includes tires & lugs)
Fits Celica, Corolla, Matrix, and Scion TC. (No natural Mazda fitment, but maybe someone here has an OTM that could use them? Centerbore is 54.1 IIRC -- which will also be somewhat limiting.)
No rash or bends -- these are in darn good shape. Includes a full set of the required flat-seat lug nuts. Tires are a matched set of Dunlop SP8000 with good tread, but they are quite old.
