There is no such thing as a "tune up" for any vehicle. Scheduled maintenance and repairs are all there is. It depends on what year the Ferrari is. Early V-12s take time, later V-12s take time. Valve adjustment on say, a Daytona takes a long time purely because of the amount of parts that need removing. The distributors always need disassembling and checking, all of the carbs need cleaning so on and on....
Later cars have more electrics and most have timing belts.

As Tabs said, "if you have to ask, you can't afford it"

The early 308 and some of the V12 cars are DIY Ferraris, anything late isn't.
