probably gets like 20 mpg driving around town maybe a little more. On the SAS for extra it all depends on what you want done.
Ill sas it with a stock axle and Highsteer, rears up front, 2" lift shackle, and then chevies in the rear all ready to roll for $1500, after that ill throw on anything else you want for a reasonable amount of money up to fully building the thing if you want. It would be an AWESOME family wheeler without a doubt
