Aside from the need to take an extended test-drive in any model that you are considering, you need to make sure that the car in question has power-operated seats.
An “8-way” power-operated seat will allow you to adjust the tilt of the seat cushion, so that the front is lower than the back, and it will allow you to elevate the seat so that it is high enough from the floor of the car. The newer power seats also allow you to adjust the inclination of the seat back in tiny increments via a switch and they have power-operated lumbar support.
All of this means that you can’t even consider low-end models. Only the top trim level of a particular car model is likely to have these seats. As long as you can pay for a top-trim model, you should be able to find a power-operated seat that meets your needs.
