-Deora II (name of a Hotwheels in-house design, specifically the Highway 35 trim)
-Suzuka II (cover art/car for Hotwheels Velocity X, childhood icon)
-Literally anything you want from the Warhammer 40k universe. This is where I personally think you are one and only in regard to handling scale, what little there is from this aesthetic/theme is amazing and epic but needs some love in feasibility for us survival players.
-Your own iceboat track or rollercoaster, highway, race course, Touge Roads, etc. Either completely self-contained or modular but only someone who's built as many vehicles as you have could make likely what would be by default the best one out there if ever it was to be.
Apologies for long answer, but figured I'd take full advantage of you taking suggestions :) Thanks!
