Hello all. I was browsing the net in search for a 240Z car club and saw your sight. I have a question. I have the chance to trade my 1990 Honda Civic Hatchback for a 1970 240Z. It has recently been restored. The body is good with a very nice paint job. The steering seems tight and straight. It has a 2.4 OHV 4sp. Which runs good. The seller says it will ping and some times deisol unless he runs on Chevron fuel, 89 octane. I would run higher octane, would that cure this problem? Or is there other variables to look into? The interior is in very good condition. He is askeing 2800 for it, and will trade instead. I am not very knowlegable on Datsuns, I just know allot about Hondas, so any advice would be appreciated. I have loved 240's since I can reamember, I saw it on the side of the road and I was hooked. Thanks, -Ben
