Where to find detailed info about rally cars?

Hi Guys;

I am after detailed informations about rally cars. such as a preview, their tech specs, success, produced years, driver info's etc...
any web site you guys can share with me to find detailed informations about the rally cars we are collecting...

thanks
Omer

Here are some that I have found with good info:

http://www.juwra.com/teams.html - click CURRENT WRC TEAMS or PAST WRC TEAMS to see manufacturers. Click on a manufacturer to see some info on the cars.
http://www.rallye-info.com/carmodels.asp - select a class from the drop down to see a comprehensive collection of cars from each class (i.e. Group 4, Group B, etc.). Some cars have a lot of detailed info, some not so much.

this is what I was looking for mate!
thanks for attention and quick respond
