Having certain expectations from people driving luxury vehicles

When i first bought my expensive car there was always a certain expectation from people. That i had to be this proper good girl that always looked her best. I used to dress from thrift stores and never fix my hair. People never believed i owned such a car they always thought it was my fathers that i was borrowing. There were many times where i had given my car to a valet parking and when id go back to get my car i was treated horribly and shunned away until the specific valet person who took my car from me would get it back. I feel now that i always have to look my best and act a certain way to make people believe that i come from a certain class. That the car i own is actually mine.
