I'm sure there must be a simple way of doing this ...

I have 2 columns of data:

A1:A2000 contains data of vehicles used to transport goods
B1:B2000 contains the dates on which each vehicle was used over the space of
several years

There are many duplicate entries in each column (ie; one particular vehicle
will appear many times as will any given date).

I simply need to set-up a summary that shows:

1) The total number of times each vehicle was used
2) The earliest date each vehicle was used
3) The latest date each vehicle was used

I have resolved 1) using SUMPRODUCT but can't at the moment work-out the
answer to 2) and 3). VLOOKUP comes to mind but maybe there is another
SUMPRODUCT solution?

Thanks for any help.
