Hello Rob,
I was randomly reading up online on my car, and stunmble upon your question and was like i have got to sign up and respond.
Absolutely not, thats not okay. That information should have been disclose to the purchaser.
You should blow them up for this, its unacceptable.
I strongly disagree when people are cheated and robbed and ripped off.
I always do my research before going to them.
I hope this helps.
