I was in for the annual checkup and my salesman Brad
I was in for the annual checkup and my salesman Brad Biondo had reached out to me via email with an assessment of my 2020 car. So I stopped by. Ha- now driving a 2026. That wasn’t the plan. I continue to be impressed with the upgrade. Huge difference in performance and attributes. Brad made it all to easy. Super knowledgeable, reliable, with integrity- highly valued.
This truck has a jerk when changing gears sometimes.
