Xav,
You have been critical of Tesla's leases (except for inventory P90Ds), but haven't posted much in the way of comparative data to support your statements. From what I have seen, I don't think the criticism is justified, particularly for the two-year lease.
I have always bought my cars instead of leasing but as noted upthread decided to jump on the new two-year lease deal. I started by looking at a two-year lease on a fairly stripped down S60, which start at $593/mo before gas savings. When I researched two-year leases for comparably priced cars, Tesla's payments appear to be not only competitive but far cheaper than the other leases I found.
For example, a 2-year lease on a Mercedes E400 (MSRP $60,650 -- about $5K less than a Model S) with $5K down is $1013 per month. A two-year lease on a 2015 Lexus GS 450h (MSRP $61330 -- also about $5K less than a Model S) is going for $1255 per month with $5K down -- more than double the monthly payment for the higher priced Tesla. I looked for comparable BMW two-year leases but did not find any. To try to get as close as possible to an apples-to-apples comparison, I chose 10,000 miles for the Mercedes and Tesla leases and 12K miles (the closest available) for the Lexus.
From what I have seen, monthly payments for two-year leases for other companies are typically significantly higher than for a three year lease -- presumably because most depreciation takes place in the first year (that new car smell is expensive ....). Tesla's lower rates for a two-year lease, however, can take advantage of the $7500 federal tax credit and Tesla's relatively good depreciation rates, resulting in terms that based on my (limited} research appear to be far less expensive than even lower priced cars from other companies.
I was lucky enough to find a demo pre-refresh P90DL with 9,000+ miles and some repair work done and got what I thought was a very good deal ($893/month before referral credit). So I decided to plunk down a little extra for all the bells and whistles on a demo/inventory P90DL. But IMO the two-year lease on the base model was also an excellent deal as far as two-year leases go. Short-term leases are not for everyone, but the S60 lease appeared to me to be a good deal for someone who is interested in a Model S but may want to turn it over in a couple years for whatever reason (in my case, to buy a Model 3 or Y).
