A simpler understanding for all of us... Put a little perspective on it all.
There are two types of people in this world. These two different types are going to buy a new car. Magically they narrow it down to the same two cars.
Car A is a v8 with 350 horsepower. It is foreign so the customer service is pretty shabby. Parts take a long time to get in, they don't give you a loaner car when you do need repairs, and you have to buy the car before you even get to handle it.
Car B is a v6 with 330 horsepower. It is a foreign car too but it is sold through a domestic dealership. The dealership stays in business by providing service to this car. They keep parts in stock, they will be in your area to answer questions right away, and if god forbid your car is a lemon they will replace it or loan ya something while you wait for repairs. It's got a little less go but gets 5 miles more per gallon and has a sweet leather interior and cool cockpit displays.
Type of person 1: Goes to dealerships and says I need the car with the most power. It has to be at least a v8 with 350 horsepower. The domestic dealer tries to persuade him to his car. Listen all I have is a v6 but it only has 20 horsepower less then the v8. You also get better gas mileage so you don't have to stop for fuel every 4 hours on trips. Also it has this great interior. "Don't believe me, go take it for a spin."
Person 1: "No, sorry. It doesn't have a v8. It's not good enough for me."
goes to foreign dealer. Dealer says, "I don't have one here but if you pay for it I'll get you a v8 car." Person 1 agrees and buys car A.
Type of person 2: Goes to dealerships and says I need a car that is FAST. Foreign dealer says I got a v8. It is awesome. I don't have one here but if you buy it I can get it to you. Here is a brochure. Person 2 says he is going to look at this other car. He goes to the domestic dealership and they show him right to the car. He gets in it. "Man this leather interior is nice. Oh it looks like it gets a little more MPG too. Can I drive it?" Sure! Person 2 goes tearing around town. Damn this thing is FAST! Dealer says, "it sure is. Best part you can have this one right now, if you ever have any problems just stop by and we'll get you fixed right up." Person 2 buys car B not really caring about the number stuff but more about his experience with it.
So ask yourself. Are you Type of person 1 or 2? And just in case some one is real slow Car A=nexus one. Car B=Incredible. Person 1=people who are basing a decision on a number. Person 2=people who base decisions on real world application...aka the sane ones. haha
