Buy Richards and manual convert. 34's tend to have the least problems as the neo 25 is pretty damn reliable (other than coil pack issue, quick fix). It doesn't really matter what model you buy though, as long as it has been looked after. That said, yes the 34 will have the newest technology out of the lot. Dad previously owned the 34 I have now, so I knew it was looked after, and I wouldn't change to any other car... except a gtr p.s. r34 gtt, not gtst
