Luxury car owners , what car do you own ?

The title plus

• How did you plan it and at what age did you finally buy it ?
• What did you buy it for ( approx ) ? was it second hand or first ?
• How regularly do you drive it ?

as everyone on this sub I love cars and want to own a g82 m4 one day. Just wanted to get a context of how others planned it out and how its going for them.
