Hey guys, as the title says. I just saw it, it has 131k on it all power, leather, digital cluster(which i like). Also when i left it on for about 2min the service engine light came on. Now I dont have a scanner, also I know it can come on if the ac doesnt work(on this car it doesnt but the heat does. so the heater core must be good). Then I shut it off and run it again for 2 min and no light go figure. I didnt get to run the car since it has no insurance(yet it still has the florida plate). But he is asking 300 for it. also it has a new tranny that got put in 98. I saw the cadillac serivce sheet and it did say it. could you guys think of anything I should look for? tia.
