If you are looking for some cool race car sounds go to:

http://www.conceptsi.com

They have a Roadracing Sound Show cassette (OK cassette is
old tech but the sounds are still way cool) that covers most forms
of roadracing in the 1970's.

You haven't lived until you have been passed in your
own living room by two 12 cylinder Ferrari F-1 cars at
180 MPH

Absolutely makes you feel like you are at the great race
tracks of Europe. Includes sounds of Porsche, BMW, Jag,
Ferrari, Lotus, McLaren, and the unforgettable incredible scream
of the Matra

They also have large very high quality F-1 and Motorcycle calendars,
books and a World's Greatest Race Tracks poster.
