Get the factory to correct any issues, its called customer service - dont start to school me on that too, I have had Pakistan suzuki motors actually rectify a lot of faults in the vehicles I purchased.
The grading system you mention for japanese vehicles is only there for auction viewing and legality purposes as you are not physically available to see/inspect the vehicle.
With a vehicle infront of you - you can look for oddities yourself.
btw - speaking of the ABS damage, the unit is plumbed after the master cylinder, when it malfunctions, the valves do not shuttle even at startup. They can get jammed (quickly if brake fluid is old and watery) - and you then lose brakes in odd ways that make you think the proportioning valve (if equipped) is jamming. - sometimes it also fails completely on one circuit.
I know that you think its all a joke, but you just proved something yourself.
you are taking two equals here and biasing towards one because you own it, on one hand you say a PS cultus is a POS because it has bad factory work (you can get it corrected from them for free) - but on the same note you say that a malfunction JDM is kosher.
