Is it hard to install a starter? Was looking into just doing it myself....

If it's a 2.2L it's very easy. Run the car up on ramps and you can do all the work from the front. Or jack it up and put stands under the front if it won't start. At the back of the starter there is a bracket that is a bit tricky to get at but you can do it. Just make a note of where the wires go to. I put one in about 2 months ago and it cost $98 from Autozone. Came with a lifetime warranty (for what it's worth).
