Dear …
As a new purchaser of the __(Name/make/model of equipment)__, I’ve been made aware that your company is using this same __(type of equipment)__, and have been for some time now. I would love to have an opportunity to see it in actual real time operation and was wondering if you would be so kind as to spare me a moment or two of your time one day to show me how well it works for you.
May I drop by sometime to your __(office/plant/shop/facility/etc.)__ to see it in action? I would be most grateful to you if you would grant me the favor of sharing some of your expertise with me on this __(machine/system/etc.)__. Please contact me at __(contact information)__ to let me know if it is at all possible to arrange a visit with you.
Thank you kindly. I look forward to hearing from you soon.
Sincerely,
