Last night I parked my car on side street for 30mins and someone broke my driver door mirror. The mirror is fine but the housing has just shattered at top corner. I guess need to buy a new silver housing.
Does anyone know where I can buy it ? my Lexus dealer wants to sell me the whole kit and install for $900.
I looked on ebay and nothing much for 2007 ES350 ..

i had the same issue with my passenger side. mirror. it got chipped and cracked the casing.but the mirror mechanism was perfect. now the asethitic factor. since It is a 30K car.. i thought i wud repair it.. dealer said 1000
i finally bot a replacement. original from ebay for 300.. plus paid 80 bucks to get it installed.. that is close to 400. total. i am happy and have my old mirror in case i need to replace it ever.. there is no way u will get just the cover. i tried a lot.

Those part descriptions say 07 08 09, but didn't the 08 adopt a smaller rearview mirror design than the 07?

Thanks for the ebay search you sent, I will keep looking.
$400 for replacement is not bad.
