My 22 year old daughter brought this car for her little sister 2nd birthday, we decided to put it together ourselves, I read the reviews and told  her how difficult everyone said it was to put together, I am very good at putting things together, but OMG, OMG, OMG!!!!   It took us two hours to put this little car together, when we finished, I felt like I had been in a fight..... the hardest part was getting the roof together, I remembered someone used a blowdryer to soften the pieces, yes it works on the holes that you have to install the roof to, be sure to have a blowdryer, electic screwdriver (makes it easier) and a hammer with you to make the process easy and less frustrating.  I would buy this product again, my daughter loves it, when she saw it, she said "Mine" and walked around it like she was on a car lot, her sister got the red one because her car is red and she says my car is like Sissy!!!!
