Suburbans get around 13-17mpg…that’s actually quite pathetic in terms of mileage. Many smaller cars can get 3-4 times that & the smaller car would cost a lot less in repairs, tires & everything else.
Have you ever driven a Suburban before? I had one that I borrowed in Jersey & Maryland & it was a monster to park & drive. I really didn’t like that, but some people don’t mind it…but then again, they are also the people that double-park.
