Im looking for a used deleted and tuned duramax diesel 2017-2020 gmc/chevy.

I am shopping between upstate ny to Alabama. What are good places to buy?

I look on marketplace, but would rather finance via dealer than take out an auto loan thru bank.

Can put $20k down, plus another 8-10 in trade in, so looking for 35-50k

Can you help point me in the right direction?
