I see there are many sill scuff plates for the 2014 CX-5 going for less than $40 and all from China. Has anyone installed any of these and how do they compare to the OEM ones? They say they are made from Stainless Steel, but I am guessing they are of a thinner metal and perhaps they are just cheap brushed steel made to look like stainless that will rust over time. Thanks for your help, it is appreciated!
