Let me try to expand on those answers...
Different sized rims do somewhat affect your ride... Larger rims
are nicer, but do somewhat affect handling of the car... not to
mention fuel consumption... Not too sure about this, remember
reading about this quite a while back...
In a way, yes, bigger LOOKS better... but sometimes smaller rims
are better for fuel consumption...
HIDs stand for High Intensity Discharge lights... these are those
very bright lights you see on some cars these days. Some cars come
stock with them, others come as additional options... HIDs are not
just chio... they do give off a more intense light than normal
conventional headlights, but the danger is the glare they give off
to oncoming traffic that could blind drivers if the lights are not
directed to the ground. In such situations, HIDs are a danger to
other drivers as they may temporarily blind oncoming drivers,
causing them to lose their night vision and they might lose control
of the car.
This is especially so when you're driving in areas that are not lit
by any overhead lamps, where it is totally dark. If you get blinded
by HID lights, there is a risk that you might not be able to see
where you are going on the road... and might lose control of the
car...
