There's a kerfuffle today over on ffcars where a newby asked The Question That Cannot Be Asked over there, namely which car is less expensive to build, the SLC or the GTM.
While he got slagged over there, and arrows were thrown, I was thinking about the topic and came up with a small spreadsheet.
The point wasn't to "prove" anything, but to put some realistic build costs on paper so people could compare things.
I tried to compare new-to-new, as I expect that most people really don't want to invest so much time, resource and effort into a car with used parts (though I know that some people find cheapness an attribute, and the GTM seems to attract more of that crowd). And while people could argue that used parts are a less expensive way to build a car, I don't think many people would accept them on a new car they bought at a dealer, so why would they be acceptable in a new car you built?
I left off the cost of interior work, as that can range from raw and basic to really high end, though I do believe that it is ultimately much less expensive to get to a high level with the SLC than the GTM.
I also left off the subjective differences, like the fact that the two cars don't have "equal" chassis designs, and styling (for obvious reasons), but tried to account for some of the differences in how the kits are provisioned.
I also didn't account for the genuine race history on the SLC (as opposed to the "GTM-R" which is so modified in the chassis as to be a different car -it's a center-seat, center-steer car that only resembles the original chassis from a distance), though the relative speed shown by the one time a GTM actually raced an SLC (last years 25 Hours of Thunderhill, where the GTM finished 51 laps adrift of the SLC) was interesting and informative.
I also left off some objective differences, like the better brakes on the SLC, generally better quality in the SLC-provided parts (e.g., fuel tanks that don't leak and need constant fiddling, better quality shocks, etc.)
So, what does the rest of the forum think? Did I forget anything? Are the numbers wonky?
Inquiring minds want to know!
