Hi SaraBee,
I am lucky enough to own a Tahoe which is tall. It has handles so I could haul myself in and then I could just slide out. I am also tall, which helped. They do make handle things to help you in and out of your car but by the time you order it from Amazon, you won't need it!
Funny-ish story about my right hip replacement. As you can imagine, it took longer to be able to drive after that one. At 4 weeks out, my son had appendicitis. I couldn't drive him to the hospital, so his girlfriend, who had only ever driven little cars, jumped in like a trooper and drove us down in the Tahoe. (50 miles to the hospital that took our insurance). I had been so proud that I wasn't limping at that point, but didn't realize how slow I had been walking until I had to race around the hospital after my son who was being pushed very fast in a bed all over the place! I must have been quite a sight, limping along after them going "wait, wait, I just had a hip replacement!"
