There are several reasons for buying a later model 360. First the F1 ECU/TCU (electronic control unit/transmission control unit) software was updated at Assembly Number 47115, SN 1299XX (2002) and 47380, SN 1301XX (later in 02) to improve smoothness and also allow a hand entry of the point of intial clutch slippage (PIS) value. Previous editions of the software could only command PIS to self adjust and start and shifting algorithms were less refined.
For MY 03 in Summer 02, a new Motronic ECU was also introduced, but I am unsure what improvements it brought.
Also, in late 2003 a very troublesome 30 amp F1 pump motor relay, which had a tendenccy to fuse its contacts and keep the pump motor running continuously until it burned out, was replaced with a 50 amp relay.
For the Spider, in the late 01 timeframe changes were made to the top mechanism that allowed some maintenance operations to be performed without having to remove the entire top mechanism.
Somebody else can probably add to the list, the the F1 ECU/TCU was the big deal.
Note that it is relatively easy to exchange a newer 360 or Challenge Stradale F1 ECU/TCU for the old one, so I would not hesitate to buy an earlier 360 in excellent condition. There are also higher capacity F1 pump motor relays available. The 575M had the same 30 amp relay and I already have an uprated replacement for mine.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
