The problem with the Sigma is that it
was only made for two years and didn't
sell very well, so parts are scarce and
expensive. Items that would cost $150
on a Camry or Accord could easily be
$400 on the Sigma. My Sigma also had
recurring front end problems, each
front axle has been replaced twice over
the years, and it wasn't cheap. Other
than that, the car is extremely well
made and reliable, the V6 engine is a
marvel, body integrity is superb, and
the leather interior is very luxurious.
I drove my Sigma for 8 years before
trading it in, and was sad to let it
go, despite the high maintenance costs.
