Textbook on the Geometry of Special Relativity

I am looking for a textbook that treats the subject of Special Relativity from a geometric point of view, i.e. a textbook that introduces the theory right from the start in terms of 4-vectors and Minkowski tensors, instead of the more traditional "beginners" approach. Would anyone have a recommendation for such a textbook ?

I already have decent knowledge of the physics and maths of both SR and GR ( including vector and tensor calculus ), but would like to take a step back and expand and broaden my intuition of the geometry underlying SR, as described by 4-vectors and tensors. What I do not need is another "and here is the formula for time dilation..." type of text, of which there are thousands out there, but something much more geometric and in-depth.

If you're really serious about having an understanding of the underlying math, you can look at Barrett O'Neil's Semi Riemannian geometry. Chapter six is an introduction to special relativity from a very math-heavy perspective. –  Jerry Schirmer Jan 28 at 8:34
Relativity, Groups, Particles by Sexl and Urbantke will work. –  NikolajK Jan 28 at 8:44
I really enjoyed Tensor Geometry by Dodson & Poston; by rights it will give you a healthy foundation for General Relativity but treats the Special theory at the outset. books.google.co.uk/books/about/… –  Autolatry Jan 28 at 11:46

I quite liked

The Geometry of Minkowski Spacetime: An Introduction to the Mathematics of the Special Theory of Relativity. Gregory L. Naber. Dover, 1992.

It has a very formal and very rigorous treatment of the geometry, and I still find it refreshingly in tune with the formal mathematicians' way I was taught linear algebra with (e.g. Friedberg, Insel & Spence). He does a brief physical motivation for why one can define the Minkowski spacetime $\mathcal M$ as a four-dimensional vector space equipped with a Lorentzian metric, and then rolls along with that and only that.

One curious aspect is his treatment of the electromagnetic field tensor, which he treats in the mixed-form, linear-transformation-like, $F^\mu_{\ \ \ \nu}$, which is natural for the phrasing of the Lorentz force in 'newtonian' (as opposed to 'lagrangian') relativity, i.e. $$\frac d{d\tau}p^\mu=qF^\mu_{\ \ \ \nu}q^\nu.$$ This forces one to think of tensor symmetry and anti-symmetry in quite different terms to the usual, and once you get your head around it it makes it much easier to deal with index raising and lowering later on.

He also includes sections on spinor representations of the Lorenz group, on de Sitter space, and certain weird causality-induced topologies on Minkowski spacetime, but I didn't really go into them at the time - they are a bit heavier than I would expect most physics undergraduates to handle. They look nicely formal, though.
