Bought a new car.
Bought a new car. The car salesperson was awesome. First, I called to check the availability. It was in stock; 1 hour later, it was sold and he called me to let me know. Thats okay because that car was heavily discounted. I contacted him again for a car with higher trim. Over the course of one week, he worked with his manager to get me the best deal. I bought the car the following weekend. The car salesperson showed great patience, treated my family with respect and kindness. The dealership paperwork process was straightforward. No headaches. I finished in 1 hour.
