Cadillac of Bellevue

Have been negotiating with sales for almost 4 hours which makes me feeling tired. First, no discount from Costco has been applied to my price when promotion going on from Costco even though I'm Costco member. Sales talked to me if I gave them the Costco membership number, the price can be lowered, but after I gave it to them, nothing changed which made me annoyed and I asked them to stop typing my costco membership. So even I'm costco member, $1000 discount has not been applied. Second, $3300 for steps, will you agree if you're a customer? I was surprised when I saw the price because the sales told me he and his manager gave me a good price for steps and he also told me the even the most expensive steps cost $3000. Looks like they did give me this "good" price. Definitely not recommending this dealer for sales.
