1999 Subaru Legacy

I was in the process of replacing the head gaskets, head bolts, most of all the other gaskets, timing belt, water pump, valves, and other parts all of which are all brand new, in box, which I've already purchased and come with the car. I have the top of the engine off as I was in the middle of doing the rebuild. I got a new car and my mom is getting tired of having the Subaru out front of her house in Beaverton, so I may be looking to sell it. I have it under a car cover. Comes with all brand new aftermarket parts still in box. Also, it has a battery kill switch on a key fob for security.
