There was a sharp rise in demand/value since 2020 on cars like the 355 and 550, and some bit rarer but still significant in number cars like the 360 Challenge Stradale and 430 Scuderia. Especially for the 355 and 550, which exist in significant numbers, before 2020 these cars were $70-100k, but now with nice examples going from $150k-225k, it can make a lot more sense to import one from a softer market like Europe or Japan (especially since Japanese market examples are often extremely well kept and LHD), even if the cost of importing is $10-20k.
