Comments to last Tuesday’s Curbside Classic pointed out the lasting stylistic influence of the BMW 6 Series on such cars as the Acura Legend coupe. That reminded me of this out-of-focus shot I took of a 1990 Infiniti M30 last winter. I try to stick to cars 25 years and older anyway, but this is a car that has really fallen off the radar, as well as my camera’s auto-focus function. The M30 was a left-steering version of the Nissan Leopard, which in turn shared its platform and basic configuration with the legendary Nissan Skyline R31. Performance was quite another story: the M30 had a 162 hp version of the Nissan 3 liter V6, and came only with an automatic. Given its weight of 3330 lbs, performance was modest. But with the availability and interchangeability of Skyline and Nissan 300Z turbo components, the M30 is the easiest way to end up with that unique JDM-Skyline look on these shores.
