I think we would both be guessing to say which is more important, but would probably agree that they do in fact work together.
My point is one of diminishing return on investment. How much more does your impractical, unobtanium for most, all out Viper do for the brand at a 6:59 than my slightly less impractical and more obtainable and in line ACR at 140k with a 6:04 lap time? I think pretty much nothing as most people are not going to buy a 200k Viper to begin with let alone one made specifically for the track. Part of the reason the Gen IV ACR was so spectacular was it's costs. You couldn't find anything remotely as fast for anywhere near the same money.
When I say support, I'm not talking just about dealership support, but money invested in constant incremental improvements. Similar to Nissan and Porsche, which boost sales regularly. Regularly keeping the car in the eyes of customers with rumors of faster ring times, less drag, more power or DF etc. OR even a new track setup from SRT, customized track setups for owners at tracks based on the testing and lap records they achieve. All of that costs money too.
I want the Viper to stay practical so people will actually drive it at the track. At 200k, that doesn't happen very often at all, there will just more garage queens.
