I should have included the
craigslist ad before.
ad says:
This vehicle was imported into the U.S. for a Colombian diplomat in April of 1989 in Plant City, FL. The mileage is accurate and Car Fax confirmed. In 1995 this vehicle had only 7,000 miles on it!
looks pretty dirty to me under the hood, for those miles...could have had quite a few prior to getting a new speedo.
