Just an update:
Someone contact me that he had a White 89 SC and willing to sell it to me. The plus side is zero rust and nice shiny original paint (as he gauarantee it and looks like all the original decal still in proper place from the picture). Almost fully load minus a/c. The original leather seat and steering whenn still in very good shape. Milage is decent (around 155000km). Down side is (from my point of view, maybe wrong to others) he state that he did some tastefully mod but when he send me the fully mod list looks like it's a bit too extensive for me. Also, if I really go ahead for it I will be the 5th owner for this MR2 SC. Do you guys think I should still go ahead or just wait for another one?
