"large enough to transport a full set of race tires for a fun day at the track"
Within a half second my thought was, what happens when going in for warranty work, will anyone remember the marketing blather.....
BING! Just like your insurance policy, admit to racing the thing and your warranty will VERY promptly go out the window.
Clearly you do not understand and a sports car is not for you.
Handling and rigidity are not the same thing. A true sports car would never have a sunroof, there was a reason the Corvette Z06 only came in fixed hard top/non-hatchback form. Guess what else comes with no sunroof and trunk only? Nissan GT-R
Sunroof's also add to a higher center of gravity. Sticking with your Honda example, try to find a real Acura Integra Type R with a factory sunroof.
The civic is a wet noddle in comparison to a real sports car when it comes to rigidity.
If you aren't going to buy this because of the sunroof, you weren't going to buy this anyway........

No kidding. Talk about missing the point.

Nope, I'm not missing the point, but if you'd like to elaborate I'm listening about how a sub $30k car is that much better because it doesn't have a simple option that appeals to people looking for this type of car. They won't sell a ton of these cars, cutting out nice features such as sunroof's further reduces their market on this car.
Since when will a sub $30k car compete against a Z06 or a GT-R? A true sports car regardless of dollar value? I doubt we can come up with an infalable formula. OK sure you can hop the car up and make it go fast, but with enough time, money & creativity you can turn a '92 Miata with 180,000 km's on it into a 500hp, track eating monster. My SiR does not handle at all like a wet noodle compared to anything within $10k of it's original sticker price, but then compare it against an $80,000 Corvette sure it will just like an FR-S or BR-Z will.
Handling and rigidity are two different but very INTEGRAl things to the overall behaviour of a car. There is absolutely no way to explain how a 30 pound sunroof will so adversely effect the abilities of any car insomuch to make it noticeable to the 99.999% who would buy such a vehicle. Open the sunroof and you can drive it Marmaduke style if your helmet head doesn't fit. I guess old GSR Integra's and Mini's are known for their wet noodle handling qualities.
