Well, you didn't really give any real information on the format of the
data in your mileage column. However, my guess is that you've got at
least one row with just '+' in the mileage column which is not the
same thing as '+0'. You'll probably need to do a little data cleaning
and, once that's done you should definitely consider switching that to
an integer/numeric data type.
