So how about this, show up unannounced and want to test drive. If it’s in the same spot it hasn’t been jumped or charged. If it can’t start itself, new batteries before you take it home period. Take it on a say 20 mile test drive if they force salesman on you just tell him to speak when spoken to. Use the exhaust brake to exercise the turbo controls. Exercise everything, Tow Haul, Manual shift, A/C modes, Seat Heat etc. Punch it few times 0-60 style to see if it throws any codes, it won’t hurt anything if it’s warmed up.
If you like it tell them fresh oil and fuel filters, FCA extended warranty. I’ll leave price up to you.
Have fun and good luck!
