my first prius... smiley face

Thanks, ahead of time, for being a great community with such insightful answers.
I found a great deal on a 2011 with 132K salvage title... dont worry I saw the pictures from before the accident and knew the radiator was hung on zipties... 5200$ bought it and parked it for two weeks and came back to a dead battery that completely freaked me out... I had to crawl in the back to install but no worries, I made it 500 miles across California that day. Love the thing already 46mpg rallying at 83mph impressed
