I totally disagree that the louvres on the Giugiaro Turbo Esprits look "cheesey", this is the first time I have ever heard someone express they dont like them.
Miura started a styling trend for louvres that lead to the Urraco, BMW M1, Delorean and of course the Esprit using them.
Lots of muscle cars also had them, Mustang, Cuda , AMC AMX 3 etc.
The Ferrari F40 also had clear louvres that were moulded into the plexglass rear screen.
Lots of now sought after and high end good looking cars used them (Miura SV's are worth a million $)
So not cheesey IMO, just not 90's.
