Websites like Leasehackr forum for CPO?

Hello All:

Along with leasing, I am also trying to look for CPO and sell it off in 3-4 years. I got to learn a lot from this website about leasing (thanks all!).

Can you guys tell me if there is any website/forum that helps understand and discuss CPO deals the way leasehackr forum does for lease deals? I am trying to buy a CPO Audi A4 P+

Thank you!

My advice - do not buy an AUdi CPO unless:
a) The car is immaculate
b) You drive a lot
c) You will keep it for 5+ years.

@vhooloo is this advice just specific to Audi CPO’s? If so, why and what is your concern?
