Audi A8
Catering to the uber-luxury market, the Audi sedan offers a popular premium model, enticing buyers with advanced Quattro AWD, luxurious features and a powerful engine. The model is the height of elegance, but despite’s its stately appearance and size, the A8 is actually built with aluminum, making it relatively agile and light. The luxurious model has been circulating on the market for a while now, and while it compares well to other luxury vehicles, its depreciation is already noticeable. The standard model with a short wheelbase, 372 hp engine version was originally $80k, but now you can find a 2012 A8 model for around $30k and for $40k, and the W12 model is even cheaper.
Cadillac XTS
The mid-sized Cadillac XTS model was initially released in 2013. Created with a streamlined, elegant design, the premium model came with a host of luxurious options. Still, it failed to make such an impact, since compared to its rivals like the CTS or ATS, it didn’t offer great driving dynamics or the same level of luxury. The market viewed the Cadillac XTS as somewhat of the middle child of their lineup. So while the XTS model with a 304 hp engine and a front-wheel drive, was originally priced at a whopping $45k, you can now find a well-kept XTS for half of its base price, making it a good deal for a mid-sized luxury sedan.
