I'm looking at buying off a lease. The dealer is offering to take the car back, certify it and sell it back to me. Can anyone shred some light on how much extra the certification process would on average add to the residual value?

A cars.com article suggests CPO would normally add between 2-8% to the used/residual price tag where premium brands would charge more. The quote I get from my dealer is about ~10%. Inputs would be appreciated!
