Good resource for car stats
http://www.carfolio.com/
It has most of the cars I have searched for and has nice detailed stats for example the exact bore and stroke of engines, things which are fairly esoteric but great for replicating in Automation.
One thing to note: If, like me, you don't know much about suspension you may wonder what suspension information like "I.MS.ARB" is supposed to mean. It's a bunch of acronyms, I don't know what all of them mean but here are a few I do:
I - Independent suspension (per wheel)
CS - Coilover Shock
TA - Trailing arm
MS - MacPherson strut
ARB - Anti roll bar
Anyone else have any car stat resources?
