Help!! Electrical problem dash, driver seat, shifter knob

[Chonklexus]

I’m looking at purchasing a 2004 LS 430. The car has been sitting for a couple of years. It required a jumpstart but would die once you removed the cables. I was able to get it started and run with a new battery. The problems I had were  

the elderly lady stated she had it maintained at a dealership and it has about 105k   
I could not see the odometer   

1. The dashboard lights were completely dark. 
2. The driver’s Seat does not move
3. The shifter knob will not shift out of park unless I depress the special release button next to the shifter after pulling out a small cover and pressing a screwdriver in to the hole   
4. the car drives but acceleration was slow in the parking lot 

I checked the fuse for the driver seat and it was good   
any advice?

should I stay away?
what should I check? What’s it worth in as is condition  ?
