My local Ampera dealer is 1 mile from my house, but for a warranty repair I've been told that I have to take it to the 'local' Volt specialist, 50 miles away. I took this up with Chevrolet, as surely the warranty is provided by GM for both cars, and they are after all identical cars, but I didn't get a sensible response. Hopefully soon GM will say that Ampera specialists are authorised Volt specialists, too, but maybe the 129 don't carry much weight???
