Yes, it's worth that.
The 360 was a MUCH better bike than the 350. Unfortunately, thought the 350's were (and probably still are) a dime a dozen, the 360's about 25 cents a dozen. Restore it and it's a good, solid bike. But it's unlikely to ever be worth much because there were a lot of them and there wasn't anything particularly special about them in their day. The mundane bikes still aren't worth my. My R75/5, beautiful as I think it is, and solid as it is, was a mundane bike. From the same era (mid 70s), you've got Kawasaki H1/H2's, Suzuki RE5's, some of the Suzuki GT's, the Yamaha RD's and the earliest XS650's, and the Honda CB400/500/550. I'm sure I missed some, but those are the bikes that're currently worth something. I'm sure the mundane bikes of the era will eventually appreciate, though.
