Wanted to change some parts of our car

It's been five years that we have this Daewoo Leganza car.We love this not only we're comfortable but also an eco-friendly too since it runs by LPG, so we want to take care it as much as we can.New cars right now are very expensive.We want to bring it to the repair shop for some dents repairment and we've been contemplating if we will change some of the parts to look more nicer.We've seen some nice Daewoo rear spoilers in one of the online car shops.I'm sure it will add a distinct look to our car if we buy it.
