To estimate the price of the 2023 Toyota Land Cruiser GX.R V6 3.5L Twin Turbo GXR3 LS (Mid+++), I first looked at the selling prices of similar cars. The closest match is a 2023 Toyota Land Cruiser V6 3.5L Twin Turbo GXR2 (Base++) with 11000 km sold for 254000 SAR on 2024-04-13. Given that the GXR3 LS (Mid+++) is a higher trim, it should be priced higher. I also considered a 2021 Toyota Land Cruiser V8 4.6L GXR3 4.6L (Mid++) sold for 223000 SAR on 2023-11-12, but this is an older model with a different engine. The listed prices for similar cars range from 280000 to 325000 SAR, with the most relevant being a 2023 model with 27000 km listed for 316500 SAR. Considering the higher trim and mileage, I adjusted the price downwards from the highest listed price to account for market conditions and depreciation.
