For me it is peace of mind. Everything has to be perfect in my car. Little noise here and their within my car make me go crazy until i know the reason behind it. if i need to sum it up it will be as below.
1. Reliability - Shouldn't break apart as soon as it runs out of warranty.
2.Resale Value - Sometime if a ghost of changing car comes to my mind out of nowhere- it has to be disposed of quickly.
3. Interiors - Creature comfort, features, gizmos, safety aspects etc.
4. Performance - Speed, Agility, Driving pleasure is PRIME.
5. Exteriors - If it's pretty or a head turner, works as an added advantage.
