There's nothing wrong with my engine but I would like to replace it or upgrade it because it has over 230,000 miles on it
Cost of replacing a 230K engine, nothing wrong with it on 2000 Toyota Celica
These engines have a good track record you should get 300-350 miles no problem.
I have seen them run 500,000 mi. just keep it serviced and drive it! Use Toyota or top quality parts.
It's a TOYOTA , it's just gotten broken in! My wifes' Camry just turned 300K last week .......still got at least another 100K to go! She keeps it clean , and she likes it.......works for me.
