Those are actually very good numbers for a brand new model, I just hope the 2.0T Sport 6MT has similar, but probably not.
For the lease vs. buy comparison, my credo is "lease new cars or buy used". The 2 times I bought brand new cars is only because I got crazy good deals:
2001 Ford Mustang GT Convertible 5MT: MSRP $29k and paid $24k OTD (MI sales tax is 6%). This was a dealer demo which had just over 1200 miles, driven by the staff.
2008
Infiniti G35S Sedan 6MT: MSRP $37k and paid $29k OTD. Stacked Nissan VPP-A plan (Employee discount) with year end incentives and rebates, plus a very eager dealer to dump a RWD manual sports sedan in Michigan in December.
My lease payment target is always 1% rule; meaning monthly payment including tax is 1% of MSRP. Of course there are many variables, but I never put money down unless it is refundable MSDs, or just 1st month payment and startups.
However, I have beaten the 1% rule for my past few leases. The best least I ever had was my 2016 Hyundai Genesis sedan AWD: $42.5k MSRP and I leased for $283/mo for 12k mi/yr for 36 mos. So now I've spoiled myself. My wife's last two QX60 leases have both been $335/mo on a $47k MSRP vehicle. Some brands lease better than others.
Let's hope Genesis doesn't kill lease programs like Kia did for the
Stinger. Even at 1% lease rule, I wouldn't pay $500/mo for that car.
