Funny, when I saw the title, my first thought was that a real street car should see at least 10k miles per year.
You want to see v8s, but I'll be the first in line to throw the Series 2 up against a wheezy, low compression v8 of the era. Bring it, don't sing it!
I'd guess that miles driven per year is more of a geographical thing.
I've lived relatively close to where I work (32yrs now @ the same company/in the same city). I hate sitting in traffic. Where I live, a 30min drive on the highway @ 10pm during the week or weekend is usually a 1-2hr crawl during drive time hours. So I stay/live close to where I work intentionally. I prob average 20miles/day. I put maybe 6500miles a year on just 1 vehicle if/when that's all I'm driving but I've usually always had 2 or more and that's not including my significant others ride(s).
During this period of time, I've had:
74 Camaro Z28: 350/4spd
67 Chevy short fleet/wide p/u: 6cyl/3spd > 468/400, no power accessories
75 Camaro: 350/350
80 'Bu: 231/350
79 'Bu: 229/3spd
79 El Camino: 350/350
93 Mustang: 5.0/5spd (x-HWY/SSP & 1st EFI w/OD late model vehicle)
68 Chevy short fleet p/u: 6cyl/3spd, no power accessories
74 Chevy short fleet p/u: 350/350
83 Isuzu short fleet p/u: 4cyl/5spd
81 El Camino: 229/350
79 'Bu: 305/350
89 Chevy CC Dually: 454/400/TBI
64 Chevy short fleet p/u: 6cyl/3spd > 350/700r4
90 Chevy short fleet p/u: 4.3/5spd/TBI
99 Chevy CC short fleet p/u: 350/4l80e/SPFI
78 'Bu: 305/350
I still own the 67 & 64 Chevy trucks but they're both in the rebuild phase. The 89 CC dually, 99 CC, & 78 'Bu are the current registered vehicles. I recall max mileage being about 3k on the one that's driven the most. The old pick-ups did rack up multiple 1500mile trips to various Spring/Summer car shows w/the non-OD/carb'd drivetrains. Heaters, HEI, & retro fit stereo's were their only 'accessories'. No real Winter weather concerns in Texas.
The current crop has an average of about 10mpg. The 99 & 'Bu can get between 13-15 hwy mpg's but they don't see much highway since I can walk to/from work (last 7yrs I've lived about 100yards away from where I work). The 74 Z28, 75 Camaro, & x-cop car were the only ones to ever see a strip. None were special in that regard...
