I bought my first BMW (E30 325i that I still have) when I started working as a electrician trainee at the age of 17.
After this I had an e30 touring, a couple of e34's and a E39 530DAT. After working as an electrician for 4 years, I started working as a MWD engineer (measurements while drilling). In January I was sitting in my office at the rig feeling sorry for myself because I had jo work one week overtime. I started looking at car ads and suddenly I (my bank) was the owner of an E91 325i. :P
