I'm interested in determining what sort of cars were traded in and what sort of cars were purchased through the cash for clunkers program.

Does anyone know where to find that data?

I would hope it would include fields like make, model, year, price, state, city of trade or purchase.

The stats seem to have been quoted on a number of sites. The official name of the program was the "CARS program". You can find additional statistics on the transactions here:

The "Final Paid Transaction Database" appears to be what you're looking for. It's available as a Microsoft Access database or a CSV file (described as 'text' on the site.) Here is the list of columns in the CSV file (as generated with csvcut -n)

  1: vendor_id
  2: dealer_name
  3: address_line1
  4: address_line2
  5: address_line3

Many Eyes lists one data set:

http://www-958.ibm.com/software/analytics/manyeyes/datasets/cash-for-clunkers-data/versions/1

The provenance can be somewhat suspect when using Many Eyes data, so please follow up with the donator and make sure that the data is valid.

For states, there are a few reports showing economic impact on the states where sales were made. One such report is here:

This report also lists links to several other data sets where they pulled their data.
