I went in to my local dealer for a test drive and they found my employer was in A-Plan. I would imagine that emailing Volvo works fine too. There is supposedly an equivalent incentive from truecar (look around the forum). Before I knew I had A-Plan, I tried to get this but I couldn’t get it to work. Anyway, definitely see if you have A-Plan first. My company’s internal website didn’t mention it at all but we had it.
This thread has the lease parameters for both 2017 and 2018 S90s. It’s easy to see in the 2018 numbers that they offer lower MF to offset trims that have lower RV. @cheapdad00 pointed out there’s a sweet spot at 24 months for the 2018 Inscription. The other thing that is important is the HSE allowance. FWDs have lower FSE incentives than AWDs ($2,750 vs $4,500), so you might as well go for AWD… it’s basically free! The lease incentive is also $5,500 for 2017 vs $4,250 for 2018. Beyond that, it’s a matter of which trims you can afford and how many cars there are. I might be able to afford an Inscription that is heavily discounted, but I would need to be around $60K MSRP, and I haven’t seen many 2017s Inscriptions at that price.
