Just acquired the Lexus sc430. Anything I should watch out for with a 100,00 miles on?
Did you have the car checked out by your mechanic before you bought it? (I’ll guess, No) Doing that would have answered your question from a person with their eyes and hands on the actual vehicle.
Any car with 100K miles is so much more dependent on how it was maintained by previous owners than any brand history. Lexus may be a Toyota but the previous owner may not have maintained the car even to Lexus’ recommendations, let alone what we here would consider proper.
