John Jeide has a 2007 Myers Motors NmG, extremely similar to the Corbin Sparrow. He purchased the car needing a full set of batteries, and has just done a complete set of new batteries with Optima Deep Cycle batteries. Range is 30 miles +/- obviously depending on your terrain and driving style. Absolutely a blast to drive, and freeway speeds are possible, as it is electrically limited to 76 MPH.
I have driven this NmG, it runs extremely nicely. We have never taken an MnG to a show where it does not gather the most attention. Even trips to the corner store become conversations as everyone asks questions. Call John Jeide on his cell 630-740-8826 and discuss this very unique EV. Come out to Lemont, and drive it around.
