You had me in the first half of this comment, then you had to go and humble brag about being "able to afford two R's if you wanted to." To top it off, you make an even dumber comment saying cash is king.
First of all, people who can actually afford two R's don't tell people on the Internet, they can if they want, in an attempt to make OP feel like shit.
Second, if he financed and got a rate that works for him, who TF cares? It's his money. Asking if there are free mods to be done is exactly why car forums were created in the first place. Maybe he was just bored and wanted something to do on a Sunday afternoon without dropping $2k?
Lastly, cash is not king. Cash talks, but it's not king. If I can finance $65k (of an $80k truck) at 1.99% for 60 months, I pay $3.5k in interest, and if I keep that $65k in the S&P 500, it will make almost $50k in returns over that 5 year loan. Idk about you, but I'll take a net gain of $46.5k over being proud of the fact that I paid cash, 8 days a week.
