That's exactly what I did back in 1995. I wanted a brand new Cobra but did not know how to drive a stick. Ironically, it was my fiancee (wife now) that taught be the basics as I never had anyone to teach me prior, although a friend of mine tried one time to do so on an old Volkwagen.
Anyway, I bought a $25k Cobra brand new and didn't even know how to drive it. She actually drove it off the lot...then later on proceeded to nearly total the car backing it up nearly crashing into a brick wall. Honest mistake...no harm, no foul. Later that night, we went to a deserted K-Mart parking lot and after about 45 minutes, I drove it home.
Of course, that was with only 240 rated horsepower and not 390 supercharged ponies like now. The hardest part about learning is the initial off the line balance of letting off the clutch while giving it just the right amount of gas. Once you've got it, it's second nature but it can be an absolute bear to begin with. I stalled my old 95 probably a dozen or more times before getting it rolling. Some advice: make sure the car is sitting on level ground.
