My Father bought his first STi (my STi) when he was 43, drove it stock for 73,000 miles; he then put an exhaust and intake on it. At 92,000 miles he bought a 2011 STi limited and it has 550hp he is now 47. He is the coolest dad. don't worry about your age, do what you like to do! I know a guy at the age of 86 with a Corvette ZR1 and graduated from Bondurant.
