I’d make sure it’s had regular oil changes, check the condition of the brakes (the rears in particular are quick to go from the brake vectoring), and check the condition of the lower control arms. If all of those check out, it should be a solid vehicle! I’ve had two, a 15 and a 16, because the first one suffered an early death being T-boned. I get above advertised MPG and am not exactly kind to it.
