If you just rent the car when you can just get another car at the end of the lease. You no longer have to worry about the car or how much you will get from the sale.

It is a long paper trail, but if kept effectively, you will know pretty quickly if you are dealing with a car chronically "sick", or just normal car repair.

Unless you might be a certified technician with knowledge in the automatic car starter in place, will not try to set up your own remote starter.

There is no reason to experience this situation where there is a possible solution.
