This has the 3L V6 with the 5 speed automatic transmission. We have have it serviced every 3000-5000 miles.I just found this sweet build! I haven't seen in either listing which engine/transmission you have. Do you have the 2.1/7 speed or the 3.0/5 speed? Also, do you have a build sheet (preferred) or options for the sprinter cab? Specifically safety features, as it seems MB came out with a bunch that year. Also, any maintenance records would be helpful. Thank you!
