Purchased a 1980 manufactured home, turned out to be 1969. What can we do?

(Phoenix, AZ)

We purchased a manufactured home, listed as a 1980. Paid cash, now finally completed upgrades, moved in Feb now trying to get homeowners Ins.

Going through doc's getting info for an agent, and on Title it states that the home is a 1969.

WHAT???

We would have never bought if it was listed as a 1969, especially for the price we paid.

What can we do? We feel like we've been lied to and are at a complete loss.
