PLEASE be very careful with Carjam info!
At previous work we CJ'd a car which we were offered, shown to have live reg so we bought it, prepped for sale and then took for a WOF, passed, but the reg had been cancelled 2 months before we did the check. CJ said "not our fault, tough luck".
Subsequently we checked another 2 vehicles, all OK'd but checked with LTSA and both had been cancelled a number of weeks prior.
They also said I had a vehicle with a huge amount owing. As it was somewhat older I checked, sure enough, their info said my $2500 car had in excess of $120 000 (yep one hundred and twenty thousand) owing. I got them to check, and they then discovered their info had transposed a digit, VIN number was actually for a B Train. Apology, yeah right! Lost sale.
