I'm new here on AFM

so ello everyone

i have a 2001 v6 3.8L mustang automatic and it is in really bad shape
i got it from my grandmother as my first car and i would like to know if is it savable enough for me to keep it?
for starters the transmission seems to be shifting funny (feels like it shifts at wrong moments or low/high rpm where i feel jerk in the car), the power steering makes loud sounds when i turn the wheels, the door locks do not lock or unlock at all they try but no luck, power windows roll up to high to where they hit the roof when closed.
it has also been hit on the front passenger light the frame was whaled back straight but the light is still busted the bracket that holds the light in is broken, also the mass air flow thingy (sry I'm mustang illiterate) will not close and when it rains water gets in from the driver side window.
other then all that the car is fine.


(needs a wipe down though and wider rims&tires)
oh ya i also want to change it from a automatic to a manual(never liked automatics. good idea or bad?) (if i keep)
