I would also keep an eye out for internet specials on leftover 2018s at dealers in your area. It may also be worth a few calls to see if they are willing to deal. Because you are in PA, you will be eligible for the $3750 Federal Tax Credit and an extra $1000 rebate from the state, so reduce the listed price for the car by $4750.
Depending on where you are planning to buy your used Volt from, a new model may be comparable in cost. The prices I've seen on 2017s with ~20,000 miles on places like Carvana is similar to what I would expect to pay for a 2018 after credits, discounts, and rebates are accounted for.
I personally feel that many of the reported issues with the second generation Volt on this forum are the result of spammers, but generally the feeling seems to be the 2015 is slightly more reliable. All things considered, if the price were close, I would still take a second gen car with more time left on the (exceptional) 8 year, 100,000 powertrain warranty.
