I just do this for security questions but there might be other uses for this, I've seen a couple people ask how. I don't know how complete their info is but I've always found the answer I'm looking for this way.
Go to Amica.com. Enter your pros zip and see if it says its available in their area, I've never had it say not available when I tried. Click Auto under Get a Quote on the screen that pops up.
On the next screen fill out the rest of your pros address. Click start my quote.
Next screen "Are you a amica customer?" pick no. Leave everything else how it is and click next.
Next screen put your pros name and dob. Put whatever email and click next.
Next screen pick your pros gender and pick anything for relationship status. Leave the age they received a license at 16 and pick no when it asks if you completed a accident prevention course. Click done with drivers.
Next screen will bring up a list of vehicles attached to that address like this.
