they got tablet that connects to the database.
they just key in plate number how come diferrent colour/make you upcar d.

if looks the same just the chassis number/engine number definitely ok wan. they see outside same, roadtax alive, engine no modify ok d
u think JPJ so free go check every car chassis number at roadblock ??

some shops dont take car chassis without grant, since by sop you need to de-register the car in jpj first. however if the shop dare to take then should be no problem!

this part i hear from my friends in the industy lah. how accurate also i dunno. worst come to worst just leave it by roadside settle
