I just bought a 2004 WRX with 30k miles on it. The basic warranty had already expired when I bought it and I'm thinking about buying an extended warranty for it. It's gonna cost around $1500 for 5 more years and 100k more miles, but I'm wondering if it's worth it? Do WRX's have a history of needing major repairs in the first 100k miles (or 8-ish years)???
