i had one for 6 years and it was faultless for about 5 years. then stuff started to go around 240,000 kms.
Oil leaks, transmission was a little rough, overheating, dash lights are a common problem with these models. the mercury needles stop lighting up or flicker so its hard to see how fast your going most of the time.
I did love my lexy though. So comfy to drive, a real cruiser, had grunt if needed and the sound really opened up after about 4 or 5000 revs! I wish I had of taken better care of it because it was a great car.
