"Lincoln is absolutely, positively, unequivocally NOT going out of business. No way, no how, period."
Let me see if I can be more clear: No, Lincoln is NOT stopping "productions" at the end of this year. Have you seen any credible, verifiable information anywhere that would suggest otherwise? Is this even being hinted at by any reputable automobile magazine or writer, or by any source other than 2 limo owners that you know?
I don't understand why you bothered to post your question here if you're not going to believe the answers you've gotten, but I suppose that's your prerogative.
If you want to contact Lincoln directly, I urge you to do so. Lincoln's Customer Assistance Center number is 1-800-521-4140. If you go to the Lincoln website at http://www.lincolnvehicles.com and click on the "Contact us" link, you can verify this phone number and also get a mailing address should you wish to write.
Once again, in answer to your question, Lincoln is NOT going out of business!
