I'm pretty sure that holding onto my '98 Civic is more environmentally friendly than buying a new EV - especially since I only drive ~3000 miles/year (If I drove 10K+ miles/year then the calculation would likely skew towards an EV). The Civic still runs great and it's easy to repair when something does go wrong. And the mileage is quite good - ~30MPG combined (easily get 37MPG on the freeway).
