With more and more technology, it's hard to predict how modern cars today will fare over the coming decades. While Toyota isn't the most exciting of car brands, it consistently scores highly in reliability surveys and we see no reasons why most of its models won't be good for hundreds of thousands of miles (there's a reason why taxi drivers love them). Alternatively, have you considered an electric car? It might sound a strange recommendation, but they have less mechanical parts to go wrong. The Nissan Leaf is now eight years old and we hear of very few issues, as long as you're prepared to buy a new battery at some point along the line.
