I agree with your experience. Very knowledgable and you can tell he knows his stuff. It's unfortunately uncommon to find a salesperson that knows as much as we do about their cars, but he's one of those guys that is prowling the same forums as we do. I was only able to scoop him a few times...
Got me into a(n) Jerez Black e92 M3 at MSRP with no fuss. No games involved and kept me up to date with each step through production, never had to call to ask. Only 1143 miles to go until I can let 'er loose.
The dealership as a whole is a well run place, not pretentious, with friendly available staff and excellent service. We all know that BMWFS is not the best deal out there (except for some of the benefits) and Wally Spence was very helpful in getting me the best out of the available financing.
This is my second purchase (other was an 07 M Roadster)there in the last 6 months and won't be my last.
