Not sure which Volvo you looked at but i doubt the XT4 leases would beat the value of a Xc60 or V60CC
A search would show that any XT4 deal has hardly ever been shared here… which means it’s going to be a really uphill climb. How much effort are you willing to put in?
Some people really enjoy grinding dealers. Doesn’t sound like you would. For people who don’t, there’s a path of much less resistance (either replicating something yourself that’s very replicable or hiring a broker).
