Yeti 'subtle' accessories - advice please!

Just taken delivery of my Yeti in Steel Grey. Would like to add just some subtle individuality and am thinking brushed aluminium / silver mirror covers with a matching bonnet stripe might do just the job for me (the silver against the grey paint appeals). Suggestions about where I can purchase at a reasonable price. Many thanks in advance. (ps, A '2.0 TDI' 15cm decal each side on the lower part of the passenger door in matching silver might also work if I can get them?)
