It comes down to the type of starter you (the company) use. I noticed that yesterday when I was unloading a truck at work and a nearby Pilot started up, which sounded exactly like my Grandfather's 20 year old Prelude.
Interestingly as well, I even made note of it to my co-worker who was unloading the truck with me.
IMO, GM has the most recognizable start-up, particularly with the small-blocks (I could easily pick that out of a crowd of sounds). Chrysler, IMO, probably has the worst sounding start-up out there, as it always sounds like it is doing damage to the car.
Other oddities?
Volkswagen. They have an unreasonably long crank-over time, kind of a "rut-ut-ut-ut-ut-eh!" noise. I've found that older VWs have an easier time cranking over, but more recent MKIV models (using the same engine I have) crank for an odd amount of time.
