Thoughts on new to me 379

Hi all. Looking at 03 379 at the local dealer.
Asking asking 51k USD
12 front 40 rears
Ontario, canada
Fleet maintained
2.5 kilometers on ECM
Detroit 60 12.7
140,000 kilometers on stage 2 overhaul by dealership with paperwork
Fresh paint job
Fresh frame paint (used dealer paint job)
Was a 72" sleeper converted into day cab by reputable shop.
New drives and steers.
Shifter has quite a bit of play, but not to bad finding gears.
Going for a second look to check some more things out (fuse box and do a good check under the truck)
what yall think?
Thanks!
