The day before Walter White's 51st birthday he sold his Aztek for $50 and leased a brand new Chrysler 300 SRT-8. The rate on the leases fits within his Car Wash cover story.
He also leased Walter White Jr. a 2012 Dodge Challenger the same day. ("Fifty-One") Walter later abandoned the Chrysler 300 in the desert after the gas tank is struck by stray bullet and leaks all of its fuel. ("Ozymandias")
- The model, which is first seen in "Fifty-One", is actually a 2013 Chrysler 300 SRT-8. This makes sense in reality since Season 5 was filmed in early 2012; but not for the the show's universe, which takes place in 2010.
