Deal on the Q7 looks good. Total rebates is $8K; the loyalty portion itself is $2K. Just know that a new Q7 is right around the corner, if that’s something that will bother you.
As for other SUVs, a BMW X5 while cost more to lease, while a Volvo XC90, Acura MDX, Lexus TX, and Mercedes GLE will be comparable leases. An INFINITI QX60 will be less.
For your current Q4 e-tron lease, does that align with your contractual residual or payoff, or are they charging you a market-based value?
