I was in the market for a 2500 Suburban and all by me were well over $10,000 & then they looked pretty ragged inside & out. I found a 2000 Suburban 2500 for $6,500 with a pair of alum heads added to the deal. Previous owner had $7,000 worth of receipts less than 2 years old. It drove good & looked great in the rain so I bought it. With under 170K miles & market at the time I felt it was worth the risk & I wanted a project to play with.
None of the power locks, heated seats, radio, washer fluid front or rear worked & drivers seat was a bit rough. Carpet was beyond cleaning. Most items were simple fixes but alot of them. I did replace the carpet, installed sound deadening, new seat foam & new leather for all 3 rows. Been a great ride since.
Wish you well on your project.
