My best friend and I did our own private "Cannonball" back in the summer of 1978, driving his 1975 - 280Z (that I talked him into buying "new" over a 914-Porsche). We drove straight thru from Akron to Willow Springs Calif. in 32 or 36 hrs. I was so impressed with his car, that in the fall I purchased a brand new 280ZX. I've also owned an '81, '82, and a '83 ZX. The '84 300ZX (my least favorite) was my last one. Like PATPUR & KMAG, I'm indifferent towards the 350Z. I find the G35 (a 350Z 2+2 by any other name) a much better looking car. Coming from me (Mr. Two Seater) that's saying alot. It's to bad Datsun, oops, I mean Nissan, didn't have "*****" enough to simply come out with a reincarnated 240Z body style. Personally my favorite. Oh, and KMAG to answer your question as to weather all the original Zs have rusted away, I just want you to know I've got a 1977-Z from Calif. tucked away in my garage right now. It's got a perfect body, it runs, at least it did when I parked it there a couple of years ago, but it needs a complete restoration. My friend is still driving his today. It's got less than 80k on it.
As for the original question about the XF being an old or young car, I too would have to agree with what JUDDZ had to say. Mostly under 30 or over 50. Another good car friend of mine who is 38 loves to "rag" on me all the time about my cars, called me yesterday to inform me that he just saw "Col. Sanders" driving a yellow XF roadster in Cleveland. He says he sees Crossfires all the time and can't understand it when I tell him how rare they are. I told him he's probably seeing the same 3 cars over and over again. His biggest problem with the XF is that it doesn't have a V8. I told him it's still faster than 2 of the 3 vintage muscle cars that he owns , so what's the problem?
