In 97 I bought a 540I out of state because no one had the one I wanted.
A few years later I went to Fields when I wanted a an 00 M5. I was wearing jeans and a t shirt. When I enquired about a purchase I was sneered at and told "are you kidding? There is a waiting list of eighteen, you wont see one for two years!!" I called my original dealer (NW Indiana). He told me I would have one within 90 days and refused my deposit. I picked up my car after about 2.5 months.
I have also purchased a 03 M3 cab from Knauz. The are pros and are very accomodating.
I would ride a horse before I bought a car from Fields. They are very condescending and have a huge attitude.
