How bad of a deal is this?
Pretty damn bad. You need to get the selling price way down. Check edmunds and this this site to see what others are paying. You should get at least a 10% discount off the MSRP before rebates.
“Plus they’re paying off my 2 remaining payments and excess miles on my current lease, all adding up to $3,200”
Yeah, right. Are they buying the vehicle? If so, is there any equity? You may want to solicit offers on your car (try Carvana… they’ll give you a purchase price estimate in minutes). If the dealer isn’t buying the car, then it’s true they’re paying off your two remaining payments and any excess wear/tear. What is also true is that they’re rolling it into the lease. Ask the dealer for their lease worksheet and post it so we can critique it (tear it apart). Also, check the money factor buy rate on edmunds. I have a feeling they may have marked it up. PM me if you like.
