What you are experiencing is Jealousy. Jealousy is a normal human emotion; however it is one of those that needs to be consciously controlled.. as it can lead to bad things.
A good way to do this is what the others have already indirectly implied. Try to think about possible benefits and good reasons that could result from having other people with Supercoupes in your town. For example;
This means there are others in your town with similar taste in cars whom you might be able to become friends with..
These people w/ Supercoupes might have already had some trouble with their cars that you might now be having or have in the future, and can contribute greatly to your fixing the problem..
They might have experience with improving or customizing their cars, and can refer you to good sources for supplies & service..
If you think about the fact that their and your SCs make up a very small percentage of cars even in your town, you may realize its neat to know only you and a select few others have 10+ year old cars that can still compete with many modern cars, as if you're in a clan. . Kind of like having a Jeep
. Of course, you would not want to induce arrogance with these thoughts as it can be bad too.
In any case, always try to avoid unwarranted negative thoughts against other people. You likely did not mean to do this, but those types of things are what lowers the quality of life for everyone in our society.
Oh; and welcome to the SCCOA epconey
