Call your Freescale Semiconductor rep and ask what they are currently promoting. I think the MPCS65 and MPCS66 series should do what you want and they are pretty high-powered 32-bit devices.
I think if it's a hobby project there should be no reason not to use a product that is end-of-lifed. You aren't going to need to order a million of them.
I think also that if you were designing a production device, there might be a cost benefit in doing the J1850 stuff in software and bit-banging it. This would be absolutely hellish to program, but cheap.
