2003 Toyota Matrix - keep or sell?

My 2003 Toyota Matrix XR with c.199,000 is still a joy to drive although I realize that nothing lasts forever. Bottom line: Do I keep driving, or do I look for something newer?

This a difficult question to answer as there are a lot of factors. What shape is the car in (especially rusting)? Has the maintenance been completed as scheduled and on time? How is it driving? If it were me and the car is in good shape, I’d keep driving it, but I would be setting money aside now to get ready to replace it when it eventually bites the dust.
