You can buy any car to have fun, but this ones a bit different.
Even highschoolers can afford this car(Given they have a decent job)
Its a purists car for people not wanting nasty lil electronic aids and a silly paddled operated gearbox(Even though an auto is available)
Its light, and looks REALLY good upclose(I just saw one in red last week, small too)
Its a Japanese car, so even before this car was in production there were already aftermarket parts for it.
Also, there may even be a Performance model of the cars respected brand, BRZ STI, FR-S TRD, GT-86 TT etc.
Theres always room for improvement, but that also raises price and could hurt the car in some way.
Ps: The Miata maybe a capable car in almost any way, wether its a destroyer round tracks or some kind of "Monster" but its still a Feminine car, every generation of MX5 has been.
