We have a Subaru Impreza and are both very tall. We asked this question awhile back and were recommended the Combi Coccoro. It won't last as long as the Maxi, but we figure by the time our first child outgrows it, the second child (hopefully) will go in the Combi and we'll buy a cheaper booster for the older child.
Parents gifted it to us, but you can get it for a good discount on jet.com and I think they are running a 15% off promo for new jet.com customers too.
We haven't installed it so I can't give you firsthand feedback but I read a lot of good reviews online saying it's the best for legroom.
