I recently hit the passenger side mirror on my 2004 Touareg, breaking the casing but not the glass. I~m not sure if the motor inside is damaged. The shop I took it to claimed that you could only buy the entire mirror, and wanted to charge me $1200-$1500, which seems totally rediculous. Does anyone have experiance replacing side mirror parts (or even the whole thing) Please tell me I have other options!
