Use google sir for the sample pics. But for some suggestion, you can put I/H/E upgrade for some HP gain. For the looks siguro di ka na masyado mag eefort since ang ganda na ng mazda 3. If you want you can put wrap around skirts pero hindi ito recommended if you are living in place with lots of road hump.
for mazda 3, the looks would be enough..... just slap it on with a 17" rims and it will be fine.... HID would be also nice.
i guess the mods would be more suitable for performance like racing chips, I/H/E mods and some suspension upgrades like coil-overs, etc.
