Electric cars are finally hitting the mainstream. The 2018 model year will include the much-anticipated Tesla Model 3, with a 215-mile range, and the Chevy Bolt, the successor to the Volt, with a 235-mile range, in both an all-electric and a plug-in hybrid model. The Chevy Spark, the cute and very affordable all-electric town car with a range of 75 miles, can sadly no longer be leased, but used models are selling for an amazing $7000. Can you afford not to buy one?
