Don't forget the 135i comes with m sports bumper, m shift knobs, m steering wheel, and 6 piston brakes. All of which many people purchase for their 3 series. How much do they cost with installation? 3-4k or more? So perhaps bmw should have thrown out these goodies so the base price can start 30-32k? I think BMW included them because it wants the 1 series considered seriously.
One of the sites I found have brembo kit listed for $3360.00

Bumpers: front and back ~ 1000 - 1200?
Steering wheel ~ 470.00?
Shift knob ~ 100.00?
Labor: ~?
Not if it matters but personally I think it should have costed 35,000 out the door with leather/sports package/comfort and powered seats. With nav and cold weather as only options.
