The 2008-09 model year was probably the pinnacle years for misaligned doors and inconsistant sheet metal gaps. Approx 50% of the vehicles coming off the line were poorly assembled - especially in 2008 when they were shutting down 2nd shifts due to declining volume.
I've seen some really poorly assembled SRT8s on dealer lots in SoCal and AZ, rear and front doors drooping, front hood misalignment. Quite a few were like that...
I lucked out with my 2010... all sheet metal gaps and panel alignment are fairly spot on.
The good thing it can be adjusted, but I would take it to a body shop.
