I think it depends on what your priorities are. I like to think of this in terms of 2 classes: Tinkerer and Racer. Some people are tinkerer's, some are racers and some are a mix of both. Some are civilians, but those people dont exist in our world, they belong in limbo with their priuses
Tinkerer's enjoy the build process. They like developing a concept from imagination to reality. My friend who comes out to autocrosses is a tinkerer. He has fun driving, but he does not have the passion for it. He has ideas of devilspawn turbo e30s brewing in his head. Although he also loves class and BMW, so his ideal DD is a 750il. I thought I was a tinkerer/racer. Turns out Im a racer.
After spending a year of my life trying to prepare a semi daily turbo miata beast for track, I gave up and sold both my cars. I finally figured out that it was not worth all the random breakdowns, wasted money, cursing and sleepless nights. Ironically, this car was keeping me off the track. I bought a 2008 Civic Si Sedan and have not looked back once. Fact is, I dont mind working on my car once in a while. I change my pads for track days, do some basic work and can help out a friend. I mostly enjoy the company and good times. Rebuilding engines? No thanks! I prefer to spend my time battling at the wheel, whether it be Autocross or Track/Solo1.
Is the car slower, quiter and less flashier? Hell yes. Have I had one breakdown? Nope. I drive to the track, in complete comfort, beat the living snot out of the car and drive back. Not even a whimper from her. Warranty is nice to have. A very good stock audio system, AC (which I have used maybe twice?), power steering are all bonuses. Catching a gutted, bolt on STi? Priceless.This car opened a lot of doors for me and ironically has allowed me to get behind the wheel of some amazing and scary cars, much scarier than even my very scary turbo miata. Because I finally started getting the seat time, taking various race schools. There is no random fabricating, lsd failures or ecu codes. I can just focus on developing as a driver. Thats my thing... I get joy from being able to get inside and unfamiliar car and beat the owner... maximize the car in whatever form and conditions I am given to the best of my abilities.
Maybe you enjoy getting a car to go to speeds that it was never engineered for
? Then you my friend, are more of a tinkerer. Lets be honest, the GRM Challenge is all about that
