Retailer reviews

I got this for my grandson and he loved it! I’m not sure about how easy this is or isn’t to assemble but he has an older brother to help him! It’s nice to have Pixar Cars Lego sets because my grandsons love them!
Great gift for a child who likes LEGO and Cars.
Nice lego toy. My 4 years old enjoys it.
Nice, solid building set as usual from LEGO. However, it's a small set for that price. There are better value-for-money LEGO sets available. You are clearly paying for the Disney theme.
LEGO is always durable and educational.
Hours of fun by rebuilding the car and playing with it.
thought the pieces were larger than they actually are which was my fault for not reading closer... therefore some pieces are already lost. cute set.
My 4-year-old son can build the set himself, with our help. Afterwards, he easily creates new things from the parts. This is very educational toy.
Great toy for kids who like cars. However, some help is needed when assembling it at the age of 4.
The toy is very nice. When assembled, it's small, but my nephew really liked it. The pieces are a bit larger than normal LEGO pieces.
This is a Lego Juniors kit which includes 59 pieces. The kit contains the pieces to build a Cruz Ramirez and a race simulator. The wind tunnel fan is manual and is spun by using your fingertip. The red and green blocks are merely translucent and do not light up (though the photo on the front of the box may give that impression.)My grandson, who is almost four years old, was able to put it together with some help from me. With Juniors kits, some pieces are already put together (such as much of the chassis and the tire pegs.) There are no stickers in the kit as all of the features are already printed on the pieces.He doesn't yet know who Cruz Rameriz is but is enjoying the race car aspect of the kit. Once the movie is out, it will make playing with this car even more fun.
