The closest data point is the 2015 Jeep Grand Cherokee Laredo V6 3.6L with 106,000 km, sold for 62,000 SAR in good condition. Another relevant data point is the 2015 Jeep Grand Cherokee Limited V6 3.6L with 105,000 km, sold for 68,000 SAR in average condition. The V8 variants generally have higher prices, so they are less relevant.

The Limited V6 3.6L sold for 68,000 SAR, but it was in average condition, suggesting a higher trim level. Therefore, the estimated price for the 3.0L V6 should be around 60,000 SAR, accounting for the lower engine size and average condition.
