Dear bro, I've a 13 years old Mehran with me and tbh I am still in love with her.
Everyone has his own point of view. No doubt it is a necessity as well as a source of satisfaction, attraction and attachment.
As you said, you got bore after 15 days, but imo every passing day increases the amount of love and attachment towards the ride.
Eg, I still don't wanna sell my Mehran despite getting good offers because it's now something more than a car. May sound funny, but I consider her as a part of our family.
