First, I wouldn't even consider getting rid of a car that new with that good a reputation. We keep cars 20 to 31 years. Unless you crash it or it rusts through, it is always cheaper to fix a car than replace it with a new one. The depreciation driving a new car off the lot is more than a new engine and new transmission cost. And never ever consider the value of the car when making repairs, consider the value of the transporation the repairs will net you.
First thing we do is consider our needs. We are about to retire so we wanted two good cars going into retirement. Last July we retired my wifes 20 year old Mercury Mountaineer because we no longer needed an SUV. Of course in 20 years it was NEVER put in 4 wheel drive. Wanted a run around town car, so we got a 2020 Toyota Camry LE Hybrid. 53 mpg, room for 4 in comfort, 5 in a pinch. Never owned a Toyota before. It should be the last car we ever buy barring a car getting totaled.
2 years earlier we retired our 31 year old Suburban. No longer needed seating for 9, although it was nice for hauling stuff like furniture and making runs to the dump. Bought a Ford Flex. Instead of 9 mpg we are getting 25 mpg.
As for the process, the Internet is a great research tool. But the test drive is the biggest test. As for Consumer Reports, their data is good, but their testers opinions are no better than anyone elses. We have had a couple of cars that their testers down rated because they didn't like features, and in both cases, for us, the features were a huge plus. For example they found the arm rest height in our 1983 Mercury Lynx unacceptably low. But DW and I are tall, and we found it to be the most comfortage arm rest height of any car we have owned.
