Audi A8
The luxurious Audi A8 made waves as a premium model with Quattro AWD, luxury features, and powerful engines. One thing that makes it stand out is that it was constructed with aluminum which makes it light and agile. The current model was released quite some time ago but it continues to impress with its short wheelbase and 372hp engine. Its base price is around $80k but you can get a 2012 model for approximately $30k to $40k.
Cadillac XTS
The Cadillac XTS is a mid-sized car that was first introduced in 2013. It comes with an elegant design and plenty of luxury features. Unfortunately, its front-wheel drive and a 304hp engine did not make a lot of impact. For starters, it did not come with excellent driving dynamics and topnotch features of other models by the brand. It goes for about $45k but you can find a used one at half the price. Not bad!
