I know I'm bumping ~1.5 months later, and now it is easier to say "wait". With MS builds into November, any chance of changes brought Q1 '15 could be worth it. Seats are rumored to change. Just about every other maker has perforated/cooled, maybe movable head rests (like MB B-Class?). Maybe parking sensors become standard. Collision alert/assist? If January isn't a typical model year changeover, for Tesla, there is still the reality that 2015 Model X bundles will trickle over to the S at a greater rate than 2014 changes. They just changed a paint color, since the post above. Maybe an interior change is also in the pipe? How about that new dark gray with cocoa brown?
I don't know why anyone would look at the "model year" when reselling a Model S, when Tesla doesn't use model years. If anyone looks at a number at all, it would be the VIN.
A year can mean a $1,000 added to your excise tax bill, depending upon state. That's the one argument I'll make, here, for current/older cars.
How will that financial analysis work out if they raise the prices again?
Option prices are already pushing limits, in my opinion. I don't think Tesla has the room. What are they going to do, make Sirius XM $3,000? They are about to compete with their own depreciating cars. Until about now, new or "inventory", minus the tax-credit, has worked, but 20-50k mile cars are finally beginning to show up more than 2, or 3, at a time.
If you're pre-disposed to a new one, this doesn't matter, but I think others have also been correct to point out that a good number of MS's will be a means to get a MX. What's a car with 5k miles good for, if it isn't the latest greatest thing? Compared to next year, this one has been a seller's market. I'm getting more squimish, for these reasons.
