2000 Toyota Avalon Sedan XL 4dr Sedan
15 years and counting!
 I never thought I would ever keep a car this long but my Avalon still checks almost every box. It continues to be the roomy, quiet and comfortable vehicle that I purchased new in 2000. Had a few (not major) maintenance issues in the eighth and tenth year. Since then reliability has been remarkable. And its exterior remains relatively bright and clean even though my old house has no garage or carport. I do wash it weekly and regularly change the oil.  My two complaints are that the MPG has declined to 18 MPG in city driving.  24 MPG highway. And although the air conditioning has always worked great, it makes a short whistling sound every 15-20 minutes. Its annoying. This has gone on for over five years and Toyota cannot seem to figure out what to do to correct it.
