This was a Christmas gift to my son from his grandparents.  It has taken my husband and I TWO days to put this car together.  We looked at the written instructions, and the video instructions.  Things went pretty smoothly until we got to the part where you had to put the 2 front pillar post in the frame.  We tried EVERYTHING....from using a knife to whittle away the extra plastic, trying to hammer the post in, using cooking spray to grease the post hoping it wouild go in easier, to finally softening the plastic with a hair dryer.  Save yourself some steps and go straight to the hairdryer.  Now that it's put together my son LOVES it!
