I have only checked the mpg on the Mini two times, once it was 36 mpg, the 2nd time was 39 mpg. The 66 Tiger we used to have got low to mid-20's, so I suppose this current one, a 67 model with the same engine (289 and still using the same carb I had on the 1st one) and rear end (2:88) does too, but I haven't checked it yet. The 259 cubic inch Studebaker we just sold got 16 to 22 with a 600 Holley (jetted properly) and a GM 4 speed automatic overdrive tranny we put in it, but just to throw a spear at the gas companies, my blue & white 50 cc 2003 scooter gets 115 to 123 mpg and Karen's 50 cc 2005 red & white scooter always gets 125 mpg. !!!! Since I'm reporting mpg's, the new Maverick also shown gets 24 around town and got 30 going to Hilo and back last weekend. Not vintage or antique, but that sure is good mileage, and it runs great too, lol.
