I leased my car from them 3 years ago- not a great experience, lied to up and down, as is the norm I guess, but still blatantly sneaky . Unbeknownst to me, I left with a lease contract that had a blank mileage line (i.e. wasn't specified 12k or 15k per year lease). I asked for 15k and thought i was paying accordingly. Found out when turning my car in , 3 years later, that Bill Dube had sent a fax to Toyota a few days after my lease making my contract 36k and FORGED my signature! yes you read it right, when Toyota sent me a copy of this lease modification with my ridiculously falsified signature i was shocked. And so the battle begins (where I am now) of trying to get Bill Dube to do the right thing, just call Toyota and admit a mistake was made (not to mention illegally signing my name) so the crazy bill of going 8k mile over my lease can be waived!! Otherwise I stand to pay a hefty fine because they neither filled out the contract correctly, and additionally amended it without my knowledge! STAY FAR AWAY. I am preparing myself for the reality of actually needed legal representation. It's absolutely ludicrous they refuse to admit their mistake to the possible detriment of my credit!
