406 sedan mods

Helo ya all, i own a currently stock standard 1997 406 sedan, and i was hoping for some advise and recomendations from ya all on where and how to mod my car....i live in Malaysia, where Peugeots are rarer then BMW and Mercedes Benz...and sometimes, even Ferrari F50s for that matter (not kidding)

so...if you live in Malaysia, please recommend me some modding shops here...but of you don't, some advise on what products and mods you have done on your car will also do...and the price of those products too if possible...thanks...
