Glen Van

I purchased a 1995 SC400 two years ago from a local Lexus dealer. It is jade, nakamichi sound, stock and had only 75,000 original miles from one previous owner. I paid $12,000. Recently I added BFG e-Force tires. I love the car but now the drivers seat only pivots instead of moving front to back. The automatic forward movement does not work when the seat back is moved forward. Anyone have experience with this problem? Also, I have had two flats because the inside of the chrome rims is corroded causing a bad seal. I would love to stay with the original rims.
