2016 XC60R lease vs 2017 Base Mcan

I live in NJ and thinking of leasing an XC60 R
MSRP $52980 RV 50%??? 15K/36months 0 down MF .00042 all for $661/month
includes tax and all possible fees. Is this a good deal?

I own a CayenneS and wanted something smaller… My Porsche dealer offered me a lease for a Base Macan $759 15k/36 months $2500 at signing MF .002 2017 Macan Base MSRP $56400 10% off MSRP
Torn between both cars… which appears to be better deal?
I know the Volvo is less but perhaps the Porsche is the better deal and I love driving them.
