Thank you! great info, and yes I´ll be very careful when I pull it out. Right now its almost in"barn find" condition, tons of dust! here are a few pictures. As for its history; I don´t really know much, it was originally sold in Texas, at some point it was imported into Mexico and was registered in a State in the center of the country, the weather is rather dry and hot there and then brought to Mexico City where as I said it has spent most of its latest years stored where you see it here. Like I said before, I don´t think its too rusty, the interior is quite complete (only lacking the rear inner trim, the piece that covers the back of the tail lights), the seats, vinyl and carpet look Ok. It´s got an automatic transmission but apparently no AC (strange for a Texas car I think) Obvioulsy that´s not the original body color, it was probably white? anyway I think I´ll do something about it (or the interior color) since I´m not very much into that red on red combination. You may also notice the wrong rear end. Well it turns out that one of the original tail lights had a broken lens and since 240Z are VERY scarce here in Mexico, the closest my father could find in a junk yard was the rear panels and tail lights from a 260/280 and grafted it figuring it didn´t make much of a difference. Fortunately he kept the old (original) panel pieces and tail lights and refitting them is among my plans in a short term.
As for the engine, I believe it was working right but at some point my dad read that webers were a big thing among 240Z enthusiasts and got himself a kit with triple ones. Of course he didn´t have any experince with that particular swap (he ´d been a car collector for many years and came to had a very reasonable little collection of old and special interest cars, a well appointed garage and tools but certainly it was way over his head here) he told me that it actually started but just couldn´t get to properly tune the carbs and at some point the car started to smoke a lot, he realized that modification didn´t really suited him (since he was never into racing or high power tunning anyway), then sold the weber kit ,reinstalled the original SUs and left the car where it sits now, he probably never fired it up again.
