I am nearly 80 years and very pleased with my ‘18 Sport 2.0. I owned several Accords, ‘98, ‘02, ‘08, & ‘10. Both 4 and 6 cylinder cars. Wandering as defined by not tracking straight on the expressway is not an issue. These cars are equipped with a very comprehensive suite of driver assist features. Honda has done an excellent job with these, but she may or may not feel comfortable using them. Most have the option of being switched off. Beyond that you will like the greatly increased room in the new Accord. The power is much stronger with the 2.0 vs your ‘02 V6. My gas mileage is averaging about 35 mpg with maybe 50% expressway and 40% rural two lane driving. Very little urban driving. I have experienced no negative issues with my car. I suggest that you insist of a salesperson who can explain all these new features thoroughly.
A good reference is the current report by Car and Driver magazine in their July ‘19 issue. They evaluated the car for one year and 45,000 miles.
