I just recently bought my 2003 Subaru Impreza Outback Sport with 170k miles on it for the intention of making it a tuner... sort of. I bought the car because it was my best friend's. He had the car for about two weeks, then he very sadly got into a horrible accident (not car-related) that gave him fatal injuries. I miss him a lot and I bought the car to remind me of all of our great memories and so I could turn it into what he would've done. This is my first car that is "tunable", so I don't even know where to start.
