It is one of the best, and it's a relatively rare one year color with only 166 built. So why is it so cheap?
Compare two of their cars...
The one you are looking at..
2000 GTS Steel Grey (166 built) 10,000 Miles for $42.9
And another...
1998 GTS Silver (267 built) 16,000 Miles for $44.9
The older car that is less rare with more miles is more expensive. And the dealer is not thinking forged pistons believe me, dealers only value cars on mileage, age and condition.
And the answer to why the 2000 is so cheap can probably be found in the wording of the ad for the 98....."Shows like a 2k mile car" Any such wording is absent from the 2000 ad.
Don't buy that car without having someone knowledgeable check it out for you, easy to do in Chicago, we have a large and active group there.
And I'm going to remove the dealers link so he does not get free advertising here, feel free to pm the link to anyone you wish to consult for advice.
