I bought a 01 Diamante in 04 with 40,000 miles.
Replaced the heater core at 57,438, got it from a Mitsubishi service center for 300, had it put in for 250..
Trans went at 80,000, and I mean 80g, did all the tune ups and maintenance to keep it running good, then had to replace the park/neutral safety switch...
They always had a bad rep, and I know why I won’t talk about the 98 Eclipse.
This review came from the US, not Australia or NZ. The car however was built in Australia.
