The bottom line
The Lexus GS rewards a buyer who starts under the hood: oil leaks and fuel-trim faults dominate, so demand a leak-down test, fresh oil analysis and a cooling-system pressure check before anything else. Nearly nine out of ten cars carry at least one repainted panel, which means treat tidy paint as a red flag for prior work and scan depths yourself, yet the total lack of structural repairs keeps the bones trustworthy. Bounce every corner hard for worn shocks, then walk from any example already throwing codes or low on coolant. Use those engine issues to negotiate firmly; once the oily bits are sorted these cars stay serviceable.
