Hyundai of New Port Richey goes with MSRP only. They're the largest Hyundai dealer in the country. I was just there yesterday. They do have a $1,000 "dealer fee" which applies to all of their cars, but if I recall, when my wife bought her Elantra there, they waived half of it.
Holler Hyundai was very fair with me and truly a positive experience and recommend them highly salesman Quan Loc. See my comment on "South FL dealers". I just received white Limited and love it.
