Newcomers to GM-VOLT.COM (See here for FAQs)
Can someone please tell me if the $7500 federal tax credit begins to phase out after either:
1. The manufacturer (GM) has sold 200,000 qualifying units in TOTAL for example Volts, Sparks, Bolts ADDED TOGETHER.
2. 200,000 specific models for example Volts. Or 200,000 Bolts.
Is it by model...
