2013 Lexus GS · 129k mi — flagged: oil leaks, excessive pads wear, tires condition & wear. Inspected Aug 8.

The bottom line
These GS cars get painted often yet never show structural repairs, so the shell is usually solid even if the paint isn't factory. The real risk is the engine, where oil leaks show up constantly and often come with fuel-trim or coolant problems. Start by looking underneath for wet engine spots and checking the cooling system before you turn the key. Then test the shocks by bouncing each corner. Walk away or negotiate hard if you find an active leak plus another engine fault; a dry motor and no codes make it worth a closer look.
