I looked at a used Lexus LS400 today, 1990 model, 175K. Lady says it needs a timing belt, whats it worth? - whats good with wearing light blue swaets

The engine is a V8, beautiful, except the driver's seat and takes a bit of front bumper has a little wrinkle in it. Silver metallic blue trim, light blue leather with wood interior, all power and clean, except the driver's seat, showing minor wear and small cracks. They call for $ 1000, but I'm a little nervous because you do not run and unity. My mechanic estimated dollar 5-600 the timing belt and water pump replaced. If I buy and fix, then I'll sell a little money? Thank you!
