21 – Cadillac XTS
Introduced in 2013, XTS was a mid-size Cadillac with loads of luxury options and elegant design. However, it kind of missed its mark and it didn`t have great driving dynamics like the ATS or CTS and it didn`t have the opulence of the bigger CT6. That is why the XTS is kind of a middle child of Cadillac model lineup. The prices started at almost $45,000 for a 304 hp version with front-wheel drive which is a significant sum. But, today you can find well-kept and low mileage examples for half of the original price which makes XTS one of best deals in mid-size luxury sedan class.
