I hope you don't mind a little feedback, I do love the program but
have a few questions/suggestions.

It doesn't appear that the Refresh button updates the 'Last Import'
date/time stamp.

The Gas Prices box seems to be a bit confused. When selecting 'This
Year' as the 'Date Range', there are two sections for each gas
type. One section shows 2 'Current' lines and a 'Maximum' line.
The other section displays one line for 'Minimum'. When
selecting 'Last Year' as the 'Date Range', there is one section per
gas type and each includes a 'Current' line, a 'Maximum' line and
a 'Minimum' line. This display makes more sense and would seem to
be the desired display for all date ranges.

It would be nice to have a button bar to flip between the various
categories instead of the menu.

It would be nice if the user could default the Export folder. An
alternative would be for MyCar to remember the last folder used.

How do you clean up mileage records for deleted cars? I removed a
car that had been sold but still see the mileage records when
creating an export spreadsheet.

Again, thanks for the great program. These are not show stoppers,
but I hope you don't mind some questions/comments.
