Ideal Hyundai

I went to Ideal Hyundai dealership at Urbana Pike at Frederick today. It has been the worst experience I have ever had in any dealerships I've been to. I am not sure if it was the timing (5 PM on Saturday) or what, but the sales person was not very friendly and not very approachable. He didn't actively showed me the car or explained anything until I asked, and I didn't like at all what he said. I was considering Hyundai Elantra as my next purchase and trying to test drive one today. But the sales person didn't allow me to test drive one. He said it was a 'sale day' not a 'drive day' and asked me to return next Monday. I understand that it might be late that day and I was the newcomer at the dealership without an appointment. I was okay about rescheduling, but his attitude gave me the impression that he didn't care about keeping me as a potential buyer. I thought I would make the purchase of a new Elantra before the President's Day, but after today's experience, I may have to go back to Honda or other dealerships. Hopefully, it is only the bad attitude of this sales representative , not the entire dealership. Otherwise, I have to refrain myself considering Hyundai in my future car purchases.
