Hi,
I have a 1991 LS400 with 271,000 miles. I am the second owner buying it at 47K miles from a corporate lease program. Same engine, transmission, and maintained with new timing belts at 90K, 180K (plus new water pump), replacement of struts, etc. Only recently, have I had the Nakamichi amplifier go out. Given that it is 20 year old car w/ 271K miles, I am needing to replace the driver's side upper control arm and ball joint and both rear spindles/bushings (mechanic estimates for parts, labor and tax: $507.$493).

MY suggestion: Make sure timing belt was replaced at about 90 - 100K miles, basic review the documentation for clues on rotors/brake pads, struts, basic suspension components, and other maintenance work, talk to the mechanic who fixed the electrical to get a handle on what was done. The car is super safe, decent on gas mileage at 18 - 25mpg for city and highway, killer stereo, comfortable, handles great, and relatively low maintenance. When you have to spend for repairs, it gets pricey. You're getting a high end luxury car below NADA retail. Once you're comfortable with making the offer, try shaving 10 - 15% off with cash offer. Good luck!
