My livery includes:

27499 Carrera BMW M4 M.Wittmann, #23
SOURCES:
-Professor Motor has the analog cars (274xx part numbers) for $32.// my source
-CarerraSlots (the usa dealer) also has analogs for $32. Digital cars (306xx part #s) come with a chip you can ebay for $25; some of the vendors sell them for $45.
-ElectricDreams must be smoking something because their analog DTMs are $90, and the digital versions are $55. If you see a DTM for $36 at E/D, it is 1/43 scale.
