My 5 year old son was able to put this together by himself with minimal help from grownups. He races this car with his other technic (WHACK!) car and loves that the engine pops out when it crashes. It's been a huge hit in our house!

Fun. Hard but not difficult. Great challenge. Excellent opportunity to share with grandson. Love it!

We've been eyeing this for a while - our 4yo son is quite the Lego builder! We decided to get him this and the similar green car, "Whack!" for Christmas. The set is a big hit! He took the Bash car everywhere and loved making the bumper fly off when it crashed. He's now in the process of building the "super car" which combines the Bash and Whack sets. Very exciting build for a little boy!

Fairly quick build and fun to play with. Great pull-back function. The engine pops out when it crashes. Holds up well. Good traction and big wheels. No suspension.10 year old son loves it.
This is a Christmas present so hasn't been opened, But have previously bought this range. great value for money and a good present. You can't go wrong with lego.. unless you tread on it! Definitely would buy again.
This was the first Technic set I acquired and I immediately was impressed. It was very fun to build. It comes with a pullback motor, so that is cool. It also comes with two giant flame pieces coming out of the exhaust pipes. The three stickers for the engine and side panels are great, too. The pullback motor actually makes the car go a very good distance, and pretty fast. Now for the main feature of the build. When the car hits a solid obstacle hard enough, the trigger on the front throws the engine into the air. It’s pretty cool. You can also get the BASH!’s counterpart, WHACK!, and have them crash together and both their engines fly off. There are also pdf building instructions on LEGO.com for building both together into one big car that when it crashes, two parts ... MoreThis was the first Technic set I acquired and I immediately was impressed.

There are also pdf building instructions on LEGO.com for building both together into one big car that when it crashes, two parts pop out instead of one. The trigger is a little hard to activate if you hit it with your hand because there is not much room for it to move. It has to hit pretty hard, but when you pull it back and let it go on the floor it works great. I don’t know that you can fit a minifig inside but you can fit a LEGO Games microfig inside. Just make sure he doesn’t get hurt. Anyway, it’s a great buy for anyone just starting out Technic and the pop-off engine is great. But please don’t slam it into the baseboards of your rental house!
Arrived early perfect for special day and he loved loved it. Got it put together and lots of fun. The engine pops out if it crashes. So fun. Great toy
Quick delivery. Excellent toy the grandson loved building it and playing with it. It can really motor along on cushion flooring or laminate flooring. Highly recommended well it is lego after all.
This is a very good Technic set, especially for Pull-Back. I like the rugged tires and decals. The exploding engine works well too. But what really surprised me was the value for the money.Pull-Back cars usually have around 150 to 160 pieces, but BASH! is fairly low, with only 135. I expected it to be overpriced, but the large beams and other parts in the set make the model the same size as other $20 Technic vehicles.The only thing I would add to this set is a steering wheel. But overall, this set is better than WHACK! for sure.
Nice little pull-back action for a lego set. There is a separate set that you use together with this one to make a larger vehicle. Decent value.
