Gotta love them for trying. The facts are dealers like Salt Lake City, Naples, and Galpin, have dozens of I4's sitting. Most dealers still have their core allotments (albeit smaller) sitting as well. If they want to sell them, forget ADM's and even MSRP. They have to discount off MSRP to move these. The longer they sit, the quicker potential buyers (non Lotus familiar in particular) stop considering them. It's the non-lotus familiar buyer that they need. They already have the lotus familiar buyer in us. And, we all know that these cars will never command an ADM, unless you want to be the "I got it first" guy.
BTW, my prediction still stands, this color and all of the other classic Lotus colors will likely be offered in later iterations. This is the same playbook they've used since 2005 when the Elise was introduced in the states. Incremental changes to the same basic car to stretch the run out for 8-10 years.
