Since some (including me) seem to really enjoy the realistic look of a body shell that's more true to scale, perhaps it would be a good thing to consider running the limited 1/12th scale class (blinky 17.5) with scale looking bodies only. And then to run the mod class (or even the superstock class when it's offered) with more of an 'anything goes' rules package. Back when I ran 1/8th onroad nitro, the primary difference between the sportsman class and the open class was the body shell. Most of the more intense guys gravitated towards running open, while the more casual participants chose to run sportsman.

About the cost of 1/12th these days.............now that the brushless speedo situation has started to settle down some, 1/12th racing has never been simpler or more affordable. Only 2 lipos are needed, and they seem to stay strong indefinitely. Worries about run time have become a thing of the past. The brushless motors are also incredibly reliable and long lasting when run on 1cell voltage. The car kits (especially the CRC) are very reasonably priced. The chassis design is stable. The cars are all super durable and easy to work on. In all these ways, 1/12th racing these days is better than ever. It shouldn't be a surprise that 1/12 has been making a comeback. It is very affordable these days. Now, if only someone could find a way to keep the low profile rubber from peeling off the wheels............that would be the last remaining cost issue to be overcome.
