Dlang14,
You're in the ballpark with your estimate. Don't forget things like shipping, taxes and registration, and some of the extras your likely to purchase, such as a car cover, fire extinguisher, etc;
My Cobra is parked at the door at ERA, ready to be shipped on Monday morning. I just updated my build sheet this morning, but I won't say here how much it cost (in case my wife sees this post).
The final cost was more than I expected, but I added some extras like an aluminum coating under the hood (see my gallery for a picture) and a soft top, side curtains, heater, tonneau cover, etc;
Can't say enough good things about Peter and the rest of the folks at ERA.
Good-luck, and build in some extra cost into your budget.
Rick
