A car purchase is often a very personal thing as the car can be an extension of your personality. Consequently a simple problem can be a deal-breaker. With 2 years to go, I thought it would be useful for Tesla to have a thread of all the things that are deal-breakers when buying any car, not just the Model 3. The base assumption is that you are in the market for a $35,000 sedan. What missing features/capabilities would cause you to cross a car off your list? I'll start of with my family's list of deal breakers... the three things we check when buying any car. Fail these and the car is off the list. 1) Is there a vanity mirror on the driver's sun visor? (The lack of a vanity mirror suggests the designers assume drivers are male... or were cutting costs!) 2) The McDonalds test... are there 4 cup holders... 2 in the front and 2 in the back? (The lack of rear cup holders indicates the designers have given little regard to back seat passengers). 3) Is there back seat storage for kid's tablets, headphones, coloring books etc? (Kids spend most of their pre-teen years in the back seat. A lack of storage options suggests the designers did not consider the most important passengers in a car). True story: Two years ago I excitedly brought my wife and pre-teen kids to my local Tesla dealership as we were exploring getting a Model S. My kids climbed into the rear seats and one said, "Where do I put my stuff? There are no storage pockets behind the front seats". My wife looked at me and in that instant all dreams of a Model S vaporized. No kidding... all advantages were negated by one missing feature... and from the videos it looks like the Model 3 also doesn't have any back seat storage options either :-( So what are your deal-breakers when buying a car?
