Finding out stock drag coefficient?

I was hoping someone here has a good resource for finding out drag coefficients for older cars. In addition to the two cars in my sig, I also have a 1993 Toyota Tercel that is undergoing some engine work, and a 1973 Jaguar XJ12 that is being restored. I haven't really looked for info on the Jag, but I'm interested in getting some on the Tercel. I've googled and came up with nothing. Anyone have an inside track or any ideas?

Have you tried here?

If no luck there, you can always try to calculate it yourself. See IWillTry's Instructable:

Thanks MetroMPG. Mayfco.com had it on their site (92 is the same bodystyle). I wonder why that didn't come up on my searches...

I have looked over IWillTry's spreadsheet. Its quite impressive, however I haven't had a chance to play with it yet.

The only disclaimer about the mayfco stuff is that not all are manufacturer numbers -some are estimates. What did you turn up for your Tercel? What bodystyle is it?

According to their site it says the 92 is .36. Mine is a base trim. I was hoping for .32 which is what the newer Tercels are at (95+ models). Oh well, I'll work with what I have!
