If local tax is all that is being added to the monthly payment, yes, that is a very good non-CARB state lease deal. Especially since you're going for 12k vs 10k miles, and it's not a barebones LT.About to pull the trigger on this deal.
2017 Volt LT, base with comfort package (heated seats, mirrors, steering wheel)
3 year, 36k mile lease
$290/month (before local sales tax), nothing due at signing other than first month payment
Seem like a good deal?
