Specifically, if anyone knows the particular automotive manufacturers that received the most response from direct mailer campaingns, that would be helpful as well.

you may want to contact the NADA (national automobile dealers’ association) or the direct marketing association (dma)- either of these trade groups might have that info- in general, any response around 3-4% is considered very good for direct mail. a big ticket item like an automobile purchase (not just a test drive) would probably be much smaller.
