Delayed gratification will be a good thing in this case. It would suck having major issues with a $200k car.
It sucks having major issues with any car. But I'm going to guess that most folks buying the New Roadster will also have another car they can drive if the Roadster needs work. What really sucks is when you're dependent for critical transportation on a junker.
All that said, you can bet that Tesla is going to put every ounce of expertise and skill it has into getting the New Roadster right. This will be their flagship, showcase car, and they won't risk having anything go wrong. And if you do have an issue with your New Roadster, you're going straight to the top of the service queue, with a special phone number just for New Roadster owners. I'm not buying a $200,000 car, not even to experience zero to sixty in under two seconds. But if I were going to buy one, I'd have no qualms about getting one of the first few off the line. They're going to get this one right even if they have to release it years late (which they probably will).
