Aaah, the SEC's. Had posters of those on my walls as a kid, staring at them for hours, for years, in absolute awe, for their design, the perfect lines. A true designer masterpiece, I thought. Still do today. I still badly want one.
I been shopping around for a SEC for quite some time in the past, and in the end had to walk away simply because of the insane road taxes they charge for large engines here in Taiwan, and 280SEC's are near impossible to find here. That said, I learned from several owners that one is best off picking a first gen SEC, the ones that did not have the modern ECU systems yet. Told me that maintenance is heaps easier on those, regarding electrical/electronical issues. That is as much as I know about them. Considering how cheap they still are in a regular condition, I would expect that one needs top prepare for big repair bills along the way.
