My personal opinion is that over the past 25 years, anybody with some money backing (and maybe some connections) opened a dealership(s). I remember the day that most customers had to special order your vehicle, if you had certain color/options in mind.....now each dealer carries way too much stock IMO. When times were good with loose credit requirements, 0-2% dealer financing....it went out of control like the housing market. Just my 2 cents.
