I was quoted $800 for chrome rims.

Yes, I had good results with them on wheels for my 2011 XF, (Bought these outright, did not exchange) and on a 2008 Mercedes E350, (exchanged 17" for 18"). Price for what I got - Original equipment chromed - was reasonable.

I didn't try this website yet from your quoted price I think it is expensive from other websites.

I don't have any specific knowledge but suggest you do an Internet search for reviews to see if anything pops up.
