My 3 yr old loves being in my car. He says 'Press the red button!!', the engine start
My wife's family wagon is electric so is drama less.
It's a 5 series so is just as practical. The only caveats are that because the front seats are so big, space in the rear is less than a standard 5 and he can get his feet on the front seat backs, so shoes off policy applies! The other is as the M5 feels prestige inside, it makes you cry inside when my wife lets him eat in the car or when he vomits 😭
