Kia K900
Kia released the K900 in an effort to compete with luxury sedans. It is basically the Korean competitor of the BMW 7-Series and the Mercedes S-Class. It goes without saying that it a powerful engine, luxury features, and creature comforts. Like all luxury vehicles, it has a hefty price tag that eventually drops like dead weight. The 2015 model came with luxury features and a 420hp engine. It is relatively affordable at $60k but this was definitely not the standard price of most Kia cars. A 2-year old unit will cost just above $30k, which is not bad at all when you consider how big and premium it is.
VW Passat
The VW Passat is not exactly a luxury vehicle and it would be more accurate to call it a mid-sized family sedan. It has excellent features, state-of-the-art technology, a variety of engines, and great quality. However, people have yet to forget about the emission cheating controversy. This is why many diesel Passats have been recalled the previous year. It is also the reason for its significant depreciation. A 2014 unit initially went for $25k but now costs $12k to $13k in the used car market.
