There are a wide range of cars I would consider. Say a Toyota Camry or a Honda Accord or a Nissan Altima. Lately I have been partial to Buicks. An old Nissan Leaf with a shot battery can still go 70 miles which makes it a great second or third car in a household.
Cars from the 1996 model year forward are basically modern because they support the OBD II diagnostic standard and also the database for parts was rationalized around then. My son has a 1996 Buick and there is no problem getting parts, we considered up to about 2010 when we were looking.

Recent used cars are crazy expensive now so it not so daunting to expect some repairs on an older car, be creative looking for one that fits your needs.
