Summary Verdict

The 2002 Saturn SL1 is a budget-friendly compact car that offers basic transportation. Its primary strengths lie in its low purchase price and generally straightforward mechanicals. However, potential buyers should be aware of common issues such as oil and coolant leaks from the engine, potential transmission problems (especially with the automatic), and wear in suspension components like ball joints and tie rods. Electrical gremlins, often related to the BCM, and exterior rust, particularly in wheel arches, are also points to inspect. While not a luxury vehicle, with diligent maintenance and awareness of these potential pitfalls, the SL1 can remain a functional and economical choice.
