Panameras that are in the 2010 - 2015 range can be had for $10-20K. How much maintaining them is another question but one doesn’t have be that rich to get one.
OK...they don't age well. I've been driving German cars for 20 years and that's been my experience but for the first 50,000 miles I've been thrilled with them. And as for setting my sights higher...I,like my Depression era Dad,have always lived below my means. A $2 million Bugatti or a $500,000 Ferrari doesn't excite me. It would just make me a bigger target of some kidnapping plot.
