A $50K+ car and you want to pinch pennies on oil? Do you drive uninsured? Are you so tight you plan to skip scheduled maintenance? Expensive high performance cars require a bit more care (and expense) than a Japanese econobox. That should have been part of your cost of ownership equation.
As to the value of synthetic, it has greater lubricity, shear strength and resistance to extreme heat. Not a big deal in a beater, but it might keep things together at 8000 RPM.
