Selling a 2011 Subaru WRX STi Limited sedan, that just got done with a full build. The car itself has very low mileage also, as it was in storage for the last 6 years while the motor was being built. I bought the car with a blown motor (the common piston ringland failure), and planned on building it and then using it as my daily driver. The build took a lot longer than planned as other work and projects came up, and although I'm happy to finally have the build done, I now have other plans and no longer have a need for the car. I have most of the receipts and invoices for the car and built which are probably over $15k in total, but here's a general overview of what's been done. There's only about 150 miles on the car since the build.
