Your local guy is full of crap.
The 430 can be done as a daily driver, now it really depends on how many miles you drive though. I do around 20,000+ per year. I had to get ride of mine as it was too expensive for a daily driver for my tastes. I would have been spending 10-15,000 USD per year on service.
The car is serviced every 5,000 miles. Every 15,000 miles it needs a major service. These services are usually around 1,200-1,500 USD. The other services at the 5,000 mile intervals are oil changes. Those run around 350$.
Tires for a full set around 1,500 USD
New clutch (not flywheel) 9,000 USD at dealer 4,500 at an independent-6,500$.
Brake pads 1,200$ every 15,000 miles
Pads + Rotors $3,000-5,000 depending on independent or dealer
Clutch and the pads + rotors are the only real big ticket items. If you want a daily driver ferrari I would recommend the california, 458, FF, F12. These come with carbon ceramic brakes standard and the new gear boxes not requiring clutch changes.
