You've done your homework to check that it hasn't been registered, sold, or repaired before. If all is working well, I'd just enjoy it and forget the actuations number. You have the warranty for a year. I bought my last sports car with 330 miles on it. Some people would cringe at 300 miles on a new car. The reality is that it's been fantastic for the past 3 1/2 years and bulletproof with multiple track days every summer. No second thoughts.
