While most affordable modern cars have plenty of safety and comfort features and offer solid performance and ride quality, it's incredibly easy to tell that you're in a luxury car as soon as you sit inside one. Luxury cars are not only built to a higher standard and offer better ride quality, but their manufacturers also put much more thought into the comfort and designs of these cars' interiors, including the materials and technology they use. Therefore, there are undeniable benefits to buying a used luxury car over a brand-new economy car for the same price.

However, sadly, luxury cars tend to depreciate more than regular cars, especially within the first few years of ownership. Thankfully, just about anyone can enjoy luxury in a four-wheeler without having to break the bank.

But then, sieving through the tons of luxury cars in the market today to get a reliable one on a budget is not exactly easy. So, let's take a look at some of the most reliable luxury cars under $30,000 today.
