Go to the car dealership and see how much it would be to get a new engine and transmission installed in your 4 year old card.Only somewhat related to the OP, but I was the target of an attempted railroading yesterday on Apple Support chat.
We have an Apple Watch Series 1 that stopped working. I went through the standard steps to troubleshoot. The Apple rep confirmed that it is a hardware issue.
The price I was quoted to have this watch mailed to Apple and repaired: $205.95 (service fee) plus $14.42 (tax). So $220.37 USD total to repair a watch that can't even run WatchOS 7! 😵
For only $60 more I can buy a brand new Apple Watch SE. Needless to say, I declined the support offer.
I hate to accuse Apple of ripping off customers, but it seems that they certainly do with repairs.
Apple isn't doing anything wrong here. One option is to repair the other is to replace.
