Our 2016 Mazda 3 sport 5 manual is her primary car. Although sometimes if I need the Mazda I would lend her the GTI. She has never driven the Z though. And never will.
My wife is driving my MK4 TDI wagon - I was going to sell it after we got the GTI and she decided she liked the TDI more than her newer Civic!! I miss getting 700 miles per tank, but she has graciously offered to swap anytime!
My gf drives a 2013 Nissan Rogue SL. We used to put our great dane in my 2 door mk6 gti, which we subsequently nick named the clown car. People would laugh when they saw him get out of the car, but with the seats folded down, there's actually a lot of room. However, the Rogue is now the official dog car.
