maybe price growth can be explained those are mclaren's and ferraris - so with a time they have all chances to become rare exclusives (even in a year term, when sold out from retailors' nets). So a bit justified growth. Then again, this year's SC sets are of what i can see - better ones. Same designer that worked for TLG designing SC pioneer sets prev year now fixed his lil mistakes, like on mclaren oil-pump like we can see in new Le-mans set for instance. Sry for my english, not a native speaker.
