small car, like a Hyundai Accent? My car doesn't have A/C, and I'm debating whether or not to install window tinting or a sunroof/moonroof (manual). Tinting would be about $140, but I'm not sure if the sunroof might be a better option.

it cost about 900.00 dollars for a manual sunroof.tint is better to cool down the car compare to sunroof

The problems with aftermarket sun-roofs are many. Most if not all WILL leak, eventually. I don't even recommend t-tops or sunroofs on a new car anymore. I had a nissan 300 that leaked, and even the dealer said if they replace every seal with new, there is no guarantee it will not leak. Go with the tint.
