I'm not sure if this is hot deal, but multiple Audi dealers in southern California are unloading brand-new, leftover 2018 Audi A6 (older-design, not 2019), for as low as $34,999 for base Premium trim with no option when I did multiple e-price requests, which is far-cheaper than pre-owned certified price you pay for 2016 model year, and cheaper than most new A4s. While the leftover new 2018 Audi A6s are discounted heavily nationwide from $55,000-$60,000 MSRP, YMMV
depending on US state or dealer's policy you live in.
It appears California has the lowest-price nationwide so far. This once in a lifetime opportunity only happens once every 7 years on average, because this deal combines "last-year of old body-style" and "year-end clearance" at the same time. Nobody pays full MSRP for last-year old body style.
For starter, Audi Downtown LA has new 2018 A6 Sport trim going for $36,000 range after you click "send me e-price" request to internet sales department. Ignore the MSRP shown on your monitor screen.
While I'm not sure about other states, most Audi dealers in southern California are willing to price-match or come close to these numbers, not just Audi Downtown LA alone. Find the options you like first before which dealer to go to. Then click "send e-price," and be prepared for some jaw-drops.
As for me, I successfully purchased one from Rusnak Audi in Pasadena, CA going with Premium Plus trim for $38,000 range, $16,500 off MSRP on December 23.
Anyways, good luck to people if they're looking for one.
