Hello stosek,
welcome on board
You got a seldom combination on your hands.
Targa, LHD and Non Turbo are pretty rare in Europe - I am not sure, if there was any car regularly sold in this combination or if all of them are US imports.
I think the JZA80 freaks could help me out with that.
Any future plans on doing engine mods?
NA-T conversion or something like that?
PS: your brake fluid could need a change, just to mention
