Hi 1st post here but have been cruising and reading post. Thanks to all who provide informative information for all to see and take away what they can from it.
Was wandering about the 15-20% discounts, my dealer only gave me 15 percent discount on the exhaust after I purchased my yellow black 2012 SEUG, how can one go about getting/recieving discounts?? 
Hi Joe. Getting discounts is the same as it is anywhere else, be it a car dealer or a furniture store or your local haberdasher. You ask for a discount, then you make your purchase decision based on the reply. These days it is very easy to comparison shop thanks to the internet, so purchases other than emergency stuff can be researched for best price as well as availability. Just be careful to compare apples to apples, and always include shipping costs and taxes and fees in your comparison. Some folks offer a great price to reel you in, then hit you with stiff shipping and handling fee's.
If you have a good relationship with your dealer, and he is one of the good guys, maybe you should sit down with the boss and discuss the entire discount situation. If you plan to buy a lot of accessories and have them also do your service and accessory installs, you represent a significant revenue source to the dealer. To gain that business he should be willing to offer you better pricing than some guy passing through making a one time purchase. Rather than have to negotiate each individual purchase, perhaps you can negotiate a blanket discount for all parts and services.

As they say, nothing ventured, nothing gained.
