if so, since what year? was it optional?
Never available. However, I was wondering if it's possible to (slightly) hijack this thread, and ask a question that has interested me for quite some time: is it possible to install aftermarket Xenon's in the 355, with ballast and all? Has anybody retrofitted their car as such. The 355 has such a classic look, and I think the low-intensity discharge headlights are the only signal that the car is somewhat dated. I would be very interested in determining what kits are available.
It's definitly possible. Just buy a good kit from some place like Hella for your type of bulb, and install it in the front bumperwell. theres enough exess room almost anywhere in the front wheel well areas, ahead of the wheels.
I think the cost is gonna be a factor. Is it really worht $2500.00. Spend it on something better. I am not sure but maybe the 1999 355 Fionaro had xenons???
