I am a senior citizen grandmother and I put it together myself in about an hour. Probably could have been less, but I am an instruction reader over and over. I only needed help on the last process which you need two people for to make it right (and the instructions recommended two people as well). I got this one in particular because of the quiet wheels. Just gave it to my one year old grandson for his birthday, and he won't get out. He can't get in and out by himself yet, but that's just fine with me. Love the car!!
