I did that kit few yrs back...
The grill btw the headlights are not open.. the main grill in the centre in the bumper is open.. the 2 side vents on the bumpers are not open also...
As usual.. fujimi style... :o pram wheels... u need to lower it or add some gd wheels to make it look good. There's a kit on the Singapore Yahoo auction site... going for $17... he opened the vents and grills already.. perhaps u wanna have a look at it before buyin it frm him... if it's done well...

seems like a reasonable price ya..
Keep us posted if u are into the project..
