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.

Fun
I bought this for my husband for Father's Day. He is happily building it now in his man cave.

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. ... show more

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.

Meh
Not a fan. Asked about near-opaque engine covers, no response. The parts assemble easily enough, but you can't see anything you've worked on when done.
