Should I buy it??? (2002 Silverado 2500HD)

[ShadedSun]

Hey guys/gals!

I am currently looking at buying a newer truck.

The truck that I am looking at, is as follows:
- 2002 Silverado 2500HD LS Crew Cab, Short Box
- Duramax/Allison
- ~96,000 km
- Old oil work truck (wood box liner)
- Pretty good condition
- Sounds very tight still on test drive
- dealership asking ~$35,000 CAD (but are open to my offers)

I am very interested, but I am looking for insights on this and maybe some issues I should be looking for??

Please reply with you thoughts!

Cheers!
