Willy's Butte Speed Training Reviews
Is this LEGO set a good investment?
“While Willy's Butte Speed Training has been slightly underperforming yearly growth when compared to other sets in Juniors, at an average annual growth rate of around 8%, this set is still a decent investment for most LEGO collector portfolios.”

“10742 Willy's Butte Speed Training was my most anticipated Cars 3 set and it does not disappoint. The exclusive Sheriff looks great and I like the new sand blue Lightning McQueen too, although I have yet to see the film so am not sure how prevalent this design will be. Much... More of the scenery is equally pleasing and the printed elements are excellent, particularly since most of them could be very useful elsewhere.”
