I am 2011 WRX 4dr owner from Pomona, CA. This is my 2nd Subaru but first WRX. It's my DD and am planning to keep it stock for long time. Not really a tuner or have the $ , used it all on this car. I really haven't come across anyone in here or any other forums who actually kept it stock (I am sure there are some) but how reliable is WRX when kept stock with routine care??
