If it was done perfectly, I would like one. But I've seen some pretty crappy installs - even at dealers - that had rust, poor fit, cheesy looking switches, etc. I know there are some great installers, but it's one of those things that has to be just right, IMO. Be anal about the quality and use your best judgement!
Sunroof will decrease your car's rigity, and will therefore hurt cornering performance a bit. I think they are also heavier. I don't know if this matters to you or not, but I thought you might like to know.
when i bought my WRX it came with one... but its starting to piss me off. sometimes when it's very cold it doesnt work and now its starting to rattle so all in all im pissed i bought a car that was previously owned by a woman... at least i still have a clutch
if you autox you will lose rigidity in your car....you also have the chance of cracking it...but if you dont drive your car hard it wont really matter....then you just have 2 worry bout leaks etc....dear install for a moonroof is around 1,000....id rather spend the $ on wheels or EM
I currently have a 02 TL and the sunroof rattles way to much during the winter. When I get the WRX the one thing that I personally will not be looking for a is a Sunroof. They look pretty cool in the summer when opened, but IMO its not worth the annoyance during the cold weather.
