Bit strange it failed it’s first MOT and got an advisory for worn suspension bushes at 38,000 miles.
I would check the service history very carefully to confirm all the suspension faults were rectified by Lexus especially “misting shock absorbers”
A fail on a tyre worn down to the cords is also concerning, did the previous owner never check them? Also look at the tyres presently fitted, are they at least the same brand on axles if not all around, odd unknown makes all around would put me off.
