^^^ Cheeky is spot on. CSM is a term coined over at 4g61t.org, home of the smaller Mitsu, that also fits a 4g63t setup, and AWD if you are creative and handy. CSM = the following chassis codes: C50 (hatchback, 2 doors plus hatch), C60 (4 door sedan), C70 (look like the Eterna with the bubble back window and 4 doors plus hatch like the DSM's), C80 (AWD hatch like the C50 but solid rear drive axle and AWD setup. CSM's came with the following motors: 1.3, 1.5L, 1.6L. 1.6L TC, 1.8L. Most people refer to the USDM or Canadian Market for model year 1989 through 1992 for those chassis codes, but we only received the C50/60 versions. C70/C80 versions were available overseas from Europe to New Zealand, Australia and Japan.
