The Wyrm: A Lotus-Banzai Ghost. Think Citroën GT, and you won't be far off. It was to a Westwind 3000 what a Westwind 3000 was to a Jackrabbit.
Hawatari: Depends on what time in her life. A Suzuki Mirage while Riian is still very young; a standard sedan as Riian was growing, probably. Mercury Comet or equivalent. Once Riian was on her own vehicles, well, she would have gotten a used Jackrabbit or some such, while Hawatari returned to the speed bike.
White IC: ... there used to be an issue between electronics costs and vehicle value; it was particularly egregious on the Rolls-Royce APC. Prairie Cat? I think that's it. Anyhow, you used to be able to acquire the vehicle, replace the electronics packages (mainly the ECM and ECCM) with ones one rating point lower (null space result), and be able to sell the APCs for almost what they were originally valued at -- and the ECM and ECCM for nearly a million. With an extended hack set in order to structure 'ourselves' as individuals with valid end-user certificates, we exploited that fairly early on. Even with a relatively low percentage (30-40%), if you go to several high-end 'loan sharks' and become beholden to all the criminal organizations, i.e. none of them, you could purchase 25 of the suckers and walk away with something like 12,000,000¥ while keeping one intact one for yourself ...
Shivowtnoeh: Ford-Canada Bison (the Buffalo's predecessor) with several drone racks. I love Shivowtnoeh; only character I ever played who would set up meets in places you simply would not expect to find a shadowrunner ... or who would use spells in such creative ways.
