Is there a book on linear algebraic groups using the scheme language (i.e. not Springer or Borel, but like Waterhouse, but more in-depth)?

The book should discuss topics like Borel subgroups etc.

(Related question: Books on reductive groups using scheme theory)

allbooks mentioned here that include the Borel-Chevalley structure theory have to rely to some extent on other sources. The subject is rich but doesn't allow for a completely self-contained account of finite length: too much algebraic geometry, group theory, category theory. Milne's still incomplete book should be a useful synthesis. – Jim Humphreys Aug 1 '11 at 22:06
