Tarrytown Honda

I got an email from the dealer that they have a accord 2016 EXL at a good price.I reached out and visited the dealership.I met keith who was helpful ,i tried to bargain an little but couldn't make a deal as the manager wasn't willing to go down anymore.I got an appointment the next day to get the car.I mentioned the first day and many times over phone that i have a preapproved DCU loan for 1.99% apr and i would go with that except if i get approved for 0.9% apr promotion by honda.I had good credit so i was hoping to get 0.9.The sales person erica contacted me and asked me to send some documents,she also sent me some links so that they can look at my credit and check for eligibility on 0.9 % apr.I sent all the details.By the time i reached the dealership i saw 3 credit checks on my account from chaseauto and other banks. Surprisingly i didn't find honda finance.I rushed to the sales guy asking him why they are trying to get me a loan from banks that i didnt ask for.he had no clue and rushed to the finance person. i followed him and hear him say "i will say that i don't have any idea".He saw me outside and took me to another employee. when i asked her why she is trying to get me a finance she said she was shopping for me to get the best rate.WHAT!!!.i was really pissed off at this point.She started telling me that all the check do not effect my credit.Why should they go for others when i asked for honda finance saying that i have a pre-approved DCU at 1.99.There was a huge drama and all she said was she wasnt informed about my interest in honda or my DCU pre-approval.She came back after an hour saying that i was rejected for honda which was frustrating,she was suggesting chaseauto for 4.49% apr.Victor was the only guy who talked sense and i left the dealership as it was late .He promised me that he would try to get me approved for honda, i asked keith if 2016 honda accord exl is brand new and if everything holds good.he assured me that that is brand new and i wont be loosing anything . Next day i got a call from victor saying that he got me approved.I went to the dealership the car wasnt cleaned properly.keith assured me to get it cleaned the next time i visit the dealership.How bad is this as the stains or whatever on the car would need some kind of a machine ? i was waiting for my papers to be ready and was curious about another accord,i asked for price .A sales guy cameup and told me the reduced price and gave me the heart breaking news that if we go with the car we would loose 2 years of warranty as it was a car from 2015.I wasnt aware of it .I immediately asked victor and a couple of other about my car and they didn't have an answer.They took me to some manager who was ready with my papers.He wasn't pleasant. I started signing some documents. I asked him about my warranty ,about credit checks etc.he told me that i would loose one year warranty .i asked why wasnt i informed until now and he didnt have an answer.he was sorry about anything that happened.He looked at my file and asked me why i had to all the way from 45 miles while i had another dealership there. i came too far and couldnt go back from that. i took the car and came back dissapointed
