With the greatest courtesy
, just because the legacy dealers chose this place 30-40 years ago doesn't make it a great spot in 2016. IMO, the location as the other poster put it, is indeed a nightmare to get to any day of the week.
But I see the points in your post as valid too. Near DFW airport would have been a better compromise for all areas of the metroplex, and a fly-in option for most out-of-towners. Most of those swanky dealers are @ DFW too (MB, Lexus, Infinity, etc) with even easier delivery access for the trucks.
I have lived in Dallas a very LONG time, since JFK.
I remember when there were a few car dealers, and then almost no new car dealers except maybe VW and a Chevy dealer on Lemmon Avenue.
And lots of used car lots.
There used to actually be several cars dealers in downtown Dallas, where the Art Museum is now located and multiple blocks of dealers in current Uptown.
Eventually, most of the car dealers went where the land was cheap, out by LBJ Freeway, and maybe in the mid-Cities.
Well, the tide goes out, and then the tide comes in.
Every major premium brand is now there on Lemmon Avenue with the possible exceptions of Acura and Jaguar.
BMW bought and refurbished the former existing Lincoln-Mercury dealership, it moved in across from Lexus, Mercedes and Porsche.
And brought Mini-Cooper with them.
20 years ago, none of those manufacturers were there, maybe as few as 15 years.
MB moved over from its former Oak Lawn location.
BMW has been there like 7 years tops, moved down from LBJ and I-35.
There is a huge financial gold-mine in the people who live in the Park Cities, and areas immediately adjacent to it, Preston Hollow, etc.
Some of these homes are literally estates.
Multi-acre estates inside the LBJ Loop.
Look at Highland Park Village, Preston Center and NorthPark Mall, and the folks that work around those hubs, they shop and dine there too.
If someone is going to look for an up-market car, why would you allow your competition to go unchallenged, and not be in the same vicinity?
Marketing 101 says "Go to where your core customers (future and existing) are", especially if you are not prone to spending major dollar$ on traditional advertising during televised sporting events and news broadcasts.
The Model S and Model X are not intended to be marketed to just everybody, they are very much still a niche market commodity.
When the trickle down does comes in the way of Gen 3, it might make more sense to have a second and a third location in DFW, probably close to the Museum District in Fort Worth, maybe one more somewhere in Arlington (close to Ranger Stadium and AT&T Cowboys Stadium).
Yes, there are some swanky dealers out by DFW/Grapevine, mostly because the land values are still relatively cheap for the acreages involved and the frontage rights to the hiways.
Face it, there is a lot of traffic in North Texas.
Everywhere.
And at the rate people keep moving here, it won't be getting better anytime soon. Like NEVER.
So just grin and bear it.
Let the market decide.
