Cost of maintenance
I maintain the car as recommended by Maserati.
Once a year fluids change, and it is around $1000.00
Every 25k-35k, depends and your driving habits $4000.00 for a clutch.
Tires, one can get tires from under a $1000.00 for 4 and up to many$$$$.
It depends what your needs are.
Those cars are well built.
I have had few higher end cars. beside short life of the clutch, there is not much more upkeep expenses for this car than any other high end cars.
My car is a pure joy to drive. I use it as daily car, except of the days of the bad weather.
I hope this will help.
