He was just giving you a hard time. I would suggest looking at the F355 Buyer's Guide and then going to check the car out in person. It is hard for us to say whether or not you should buy this particular F355 as I have not seen it. I can say, yes you should buy a F355 if you want a Ferrari as it is a great car.
