I have 2001 orial prosmatec and have never faced any problem with sunroof/moonroof... Aur leakage ka to kabhi suna na dekha. If you have budget, go for orial. You will get company fitted alloy rims, door mirrors with integrated lights, sunroof, electrically retractable sidemirrors, keyless remote entry, in-dash 6 cd changer, passenger and driver airbags and foglights... add the resale and you wont even think of buying i-vtec.
My honest opinion, go for ORIAL!!!
