Blake was great! We were in and out in a couple hours. He stuck to his word, listened to us and was friendly and engaging. Never pushed us about any decision. Our fin We were in and out in a couple hours. He stuck to his word, listened to us and was friendly and engaging. Never pushed us about any decision. Our finance guy, Jarrod, was a different story. Once we refused any extras he basically threw a fit and barely talked to us the rest of our time he was with us, after he questioned us on why we made the decision we made instead of respecting it. Not a great way to end the experience. Blake gets a 5 stars! Jarrod needs to let sh;t go. 🤷🏼♀️ More
