Got this for my son for Christmas. Found it on sale at Costco for the same price. In my book Legos are never really a Slickdeal, but the build compared to others he has with similar piece counts was great in comparison. It has moving engine pieces when you roll it, it is pretty big (similar size to an rc car), and it does look pretty cool so for $40 I consider it a good buy (for legos).

Still shows in stock for me. It has been this price for the past few months so not sure this is actually a "deal".

Not difficult if you can follow the build instructions.

For 5 Euro you can download an amazing lightning dragon MOC instruction pdf that uses this kit.

My son wanted it just for that, has not even built the car yet!

Search for 'grohl' or this kit number on rebrickable if interested.
