Taking "Buying parts Who has the best prices?" literally, I have to express my appreciation for the folks at getBMWparts.com...which is to say, Tischer BMW's backroom internet "Evan and Jason operation." I recently benefitted from their regularly held customer appreciation raffles when an invoice of mine was picked from the barrel and I won a set of 19" forged, CSL M wheels. I even had my choice of staggered or all 8 inchers. I took the 8 inchers, which now, fitted with Dunlop SP9000s, are on the family's 328Ci. Look great. Over the last few months I spent a few hundred dollars ordering parts from them, and now - given my good fortune - my net cost is all in my favor! More importantly for customers, the guys know their stuff, are responsive as can be, and quickly ship what they sell...and for those of us in the DC/Baltimore area, it's easy enough to go pick up the parts ourselves. Hard for things to get much better...!!!
