Rear wheel vs mid wheel vs front wheel drive is a very important consideration. Don’t let anybody pressure you into what you do not want. You are the person who has to live with the chair for the next 5 years. Tilt, recline, articulating elevating leg rests are all features that should be easily medically justifiable if you want those features. If you can afford it, an elevating seat is an awesome feature but unfortunately most insurance will not pay for it. Make sure the physical footprint and turning radius of the chair is small enough to use in your home. A lighting package for night time driving might be nice.
