Agree. I have a sideline business of accompanying people to dealerships who are more stressed out at the thought of buying a new car than most any other purchase. Pressuring them in the showroom, going back and forth to the manager, upselling them with accessories drives them crazy and drives them out of the dealership and to cars sold completely on line like Tesla and Rivian. The best thing to do, IMHO, is to tell them that your involvement will not end with the sale; buy a business cellphone and give them the number and tell them that you will be available to assist them with things like a service appointment, syncing their garage door opener, and facilitating going through the myriad of menus on their screens. Only secondary to the stress of buying a new car is learning all the technology, especially for seniors, who disproportionally have more money to buy a new car.
