I bought my GMC Yukon through Marketplace too, and yeah, tons of shady listings there. The only site that gave me the full breakdown was carfax usa. The free ones only showed stuff like engine specs or the model’s recalls, but CARFAX gave me registration history, service records, and even the emission test logs. It revealed that the car had been registered in three different states, which helped me understand why the mileage was inconsistent. Also, flagged it as a previous fleet vehicle, which the seller “forgot” to mention. The report helped me back out of a bad deal. You just go to their site, pop in the VIN, and pay — simple and worth it.
