Two-doors are no fun with a baby.
I owned a Mazda MX-6 and my wife had a Honda Prelude. Then came baby, and I traded the Mazda for a Honda Passport.
Whenever our daughter rode in the Prelude, it was a PAIN to get her out of the cramped rear seats!
Although it's not hard to lift a ten-pound bundle of joy, your child will be using that seat for another four years...so eventually, you will have to be tugging a 45-lb bruiser out of that seat...a prelude to chiropractic complications!
Also, consider the storage capacity of whatever vehicle you choose, as you will be towing a lot of extra "camping" gear for your baby! In those early years, I was lugging more stuff than most Marine ground troops!
