A recent article on InsideEVs: http://insideevs.com/bmw-i3-three-day-test-drives-driving-sales/
"Nearly 140 BMW dealerships in the U.S. now offer the i3 on extended loan (up to 3 days-) for potential buyers to try before they buy."
Kenn Sparks, a BMW spokesperson, said “We offered the program to any dealer authorized to sell the i3,” he said in an interview. So far, he said, 138 have signed on, which is almost half of those offering the i3. Cars used in the program will most likely be offered for sale as “pre-owned. While technically a pilot, the response from customers and dealers has been so positive I imagine that we’ll keep it going.”
Some dealers have up to 4 i3s (BEVs and REXs) available for extended drives, while others will only have 1.
Demand for the test-drive vehicles is high. Keith Kubat, general sales manager at BMW of Greenwich in Connecticut, tell the New York Times that 25 people had signed up for the dealership’s lone i3 tester by early October. That books the car through the end of the year. Two who had driven this particular i3 later committing to buying.
