Used 1996 Cadillac DeVille for sale near me

I have never bought a car online before let alone bought a car without even seeing it or driving it. I saw a Bentley Flying Spur for sale at Chicago Auto Gallery. I called and spoke to a salesperson named Steve. From the first hello on the phone until we closed the deal and the car was shipped to me Steve was fantastic. He did everything possible to ensure that I was satisfied with the car and the deal. Now here's the extra part that I was even shocked at myself. Once I got the car, I drove it and after 5 miles some of the lights came on such as check engine, ride height, traction control and ABS. I was initially immensely pissed. I called Steve and said you might want to get ahold of that driver who delivered this car and tell him to take it back. Steve suggested I take it to a certified mechanic near me and have it looked at to see what was the problem. Apparently when one light goes off, it triggers more lights to activate. I had it looked at and to fix the car right it was going to be over $3000. Steve took care of it and the dealership paid the whole bill. In my mind that was the most solid thing to do and he did it. He could have argued and tried to avoid it or said no, you bought it, you fix it. They did not do that to me. I'm in Pittsburgh and they are in Chicago. I know I had rights and could have just sent it back but I wanted that car and they fixed it for me. I appreciate everything they (Steve) did for me and I would definitely purchase another vehicle from them. Thank you again Steve and Chicago Auto Gallery.

I bought my mom's 1996 Deville she bought new in 2015 a year before she passed in 2016 with 81,000 miles. I have replaced all the motor seals as recommending by GM service, transmission rebuilt, rebuilt the suspension, axles, brakes, AC/Heater, replaced gas tank, rims and tires, as well as upgraded the audio system with navigation, XM radio and Bluetooth. What I found out at my 1st service, this base DeVille was chipped for 300 hp not the base 275 and still a fun car to drive with only 114,560 miles on it and it does not burn oil, no leaks, I get 22-24 miles a gallon on road trips @ 75-80. mph As someone mentioned, if something sounds off, go get it fixed, parts are hard to find and not cheap, the repair costs are also expensive as most Cadillac dealerships do not understand how to fix it. So, find a mechanic that you trust and knows the NorthStar motor, auto ride suspension and transmission as those are the expensive repairs. But still love the car and enjoy taking it on trips.
