Cadillac XTS
The Cadillac XTS is a mid-sized car first introduced in 2013. Despite its elegant appearance and luxury features, it barely made an impression. For one thing, it did not have the driving dynamics the ATS or CTS boasted of, nor the luxury offered by the CT6. The Cadillac XTS was available for about $45k, a reasonable amount for the front-wheel drive and 304 hp engine. These days, you may find a secondhand unit for only half of that amount!

VW Passat
The VW Passat is not a luxury vehicle. It is a mid-sized sedan suitable for family use. These days, you can get one for much cheaper than its base price. It comes with modern features and technology, an expansive variety of engines, and the trademark style of a Volkswagen. While it is a good car, it has been affected by Dieselgate as well. The diesel lineup of the brand has suffered a lot, so a 2014 VW Passat formerly worth $25k has since gone down to $12k. It might not be a good idea to get the diesel version, however.
