A total pleasure to build this racing car, a feast, details are well finished, original color blends well with the assembly sticks.Côtés nothing complexe.Nouveauté "some new pieces" .The result ultimately is superb for this race car 24 hours.The dimensions are very généreuses.Côtés functions: butterflies and engine safe doors with optical undeserving Power Function "personal opinion" because electric lines of LED lights are too one can not conceal them properly and it spoils the aesthetics of the car. This lego technic, I recommend it to fans as more moi.Un in my collection, my 34 th. PS Go to Lego.com the price is much lower than that. Sincerely. PHIPHI.
