I have a 97 Toyota Corolla and almost all of it's miles are highway miles. I was wondering about how many miles I can expect to get out of it if I take good care of it and drive it well. It currently has 232 thousand miles on it. I realize there are a lot of different factors that determine this, but an educated guess would be awesome.

Also, if anyone has any tips one how to keep it running longer, I'd appreciate that as well.

Thank you!
