11 year old loved it
Son loves this! Was easy for him to assemble he could've gotten it built in one day if we didn't have to go running around perfect for his age range was definitely fun for him.

Great gift
I bought this as a gift and it was a big hit. It’s super cool and they loved it. The build is a bit challenging, but it’s worth it.

Part missing, trash. Waste of money
Part was missing. Couldn’t build past the first bag. My son was so excited to get this for Christmas only to be extremely disappointed. We learned our lesson to never buy anything without the LEGO brand name on it. I urge you NOT to buy.

Good kit, not an authentic model
For being an off brand Lego the instructions were pretty good and there were no missing pieces and everything fit together well and no bad mold pieces. It is definitely a foreign made kit by someone who has seen a picture of a V8 but doesn’t know about the actual source material. It is claimed to be a LSX454 but it is not a replica or model of. It is a fun kit but if you are looking for authenticity this is not the kit for you.

Lots of fun
This is what my nephew wanted for Christmas and he put it together the next day. He absolutely loved it. He said it was kinda like lego’s. Sorry, already deleted photo.

Super pour l'enseignement .
Je n'ai pas ouvert la boite qui ne sera ouverte que par mon petit fils dans 10 ans... Je prends mes précautions . Ce truc me semble très didactique ,et pour un prix fort raisonnable .
