Should I buy it? 1963 Chrysler Imperial

Imperials tend to be like a red-head step child among Mopars. The problem for collectors today is that there were not many of them made and a lot of the trim parts were unique to the Imperial. Check for rust in the usual places. Anything other than surface rust should be avoided like the plague.

Most of what's out there are Crown Imperials (mid-price range). Rarest among Imperials are the Crown convertible and the LeBaron (high price range). If trim parts are missing, pass on it IMHO. Other than pistons, the driveline is straight Mopar. Even in top shape, don't expect better than 12 mpg on the highway.
