Nice! I always go black for roulette
On topic though is it was me, I would put $20-25k into my Z make it how I want with FI, custom wheels, coils and other mods to taste then the other $50k I would either use it to pay down my mortgage (like others have said when you have no more mortgage your life will become much easier) or I would use it to by more equipment for my business so I would only end up making it back with additional profits and more jobs
