I don't want to name names so I'll be generic.
Wife finds car she likes. Heated seats, black, leather, SUV. I go check out car. Test drive. All good. Tell Bob (owner of used car dealer) I want my wife to drive it. Bring wife a couple days later and both her and I drive it again. We swing by my brother's house. My dad is there too (retired mechanic). Dad and brother notice fresh fuel on the side of gas tank. Go back to dealer. Ask Bob to fix two items (gas tank and another item) before sale. Bob agrees. Two weeks later, car is ready. Go to pick up car. bob is finishing up repairs on an item and informs us that only brand x's dealership 30 miles away can finish the repair. Wife and I agree to take car to dealership under the pretense that Bob is going to pay for repair. Bob agrees. I sign paperwork and head out. As soon as we hit the highway, car starts acting up. No power when accelerating, dash lights on, feels like its in limp mode. Pull over. Restart. Still same. Stop for gas and call Bob. Bob says issue may be tied to item needing repair finished at dealership. We both agree to let Brand X dealership look at it. At gas station, car randomly shuts off.
Make it to dealership. Service adviser immediately informs us of how Brand X is notorious for electrical issues (gee, thanks). Inform them of drive and what happened. Bob is called to confirm he will pay for diagnostic of new issue. Leave dealership.
Dealership calls us up (after calling Bob) and says item #1 is fixed but the issue we had on the highway is caused by $800 part. Bob says he will pay for repairs if we go with a used part he can get. We hesitantly agree.
Days pass, dealership says car is ready. Pick up car. Wife takes it. She follows me to her work. On way, car dash flashes lights. She tells me. I agree to take car back to dealership. On the way back, the car is flashing lights at me. Same as before. Ignore them. Call stalls at corner of busy intersection. Call dealership, they send a tow truck.
Day later (today) dealership tells me the engine is seized and needs more work than the car is worth.
That's where I'm at right now.
