With such low mileage, I would think checking compression on each jug is not necessary. Most mechanical shops have a SPECIFIC SERVICE called "Used vehicle check". I used an independent mechanic when I bought mine, and he charged me $99. for a 90 point inspection and printout.
check this for an example:
Checklist for Inspecting Used Cars | DMV.org
do more homework. As i have said, it is rare to get a rig with such low mileage.
