The lambocars site also refers blue alcantara for the SE30 (link) probably like this ex Jay Kay car (link) where curiously the carpet is purple like in this article about #001 (link); while in that #150 pic with purple interior they refer it was a custom order (link). My purple Jota 1:18 model has in it dark blue, but given that its a cheap Maisto, it's the the same as their SE30.
Shame that manual roll-bar adjustment in-car isn't possible, as the seems to SE30 permit it.
I already made some color combos based on pics. Need to add more carpet variations, so I'll have to do some more research on that, at least to get 5 or 6 different skins to choose from.
Done rear grille, badges
