Only thing I'd worry about is fuel economy. It's the one downside of the I6
Indeed, they are incredibly robust and durable. If properly designed they are also very efficient. BMW's Inline 6's get great fuel economy.

The BMW 340i, 3L turbo inline 6 making over 300HP gets 32MPG on the highway. That's absolutely excellent fuel economy for a rather fast car.
