actauly one piece of advice I can give you (not sure as its still valid with modern cars), is take it out for a drive on the highway and let it rip to the limit of the road.
About 5 years ago I tested some hyundai thing and once the car got on the highway (freeway) and reached over 100km/h, the stearing wheel started vibrating and when you let go, it would drift to one side haha.
