Has anyone previously owned one? How often do they need servicing?
Not that I would but could you drive it daily?
from an old fart for what its worth have owned 348ts and Spider, cam belt service is mandatory from memory 3 years I THKNK!( they extended the 355 cam belts time change) handling is an issue at speeds that should only be attemped on tracks, snap over steer at the rear, can simply be fixed by spacing the rear wheels or changing the rims and offsets
second gear when COLD so be avoided if you can find it at all until she warms up, TS roofs leak when it rains, answer DONT drive in the rain, make sure you get a FULL service history, better still get it checked out by a specialist before you buy or condition of sale
oh and check the operation of the dash controls, fans and electrics,
lastly after all this your Ferrari will stop or not start at the most in opportune times, but hell you own a ferrari !!!
