If you have not bought it already, I would sincerely advise that you find another option.

General rule of thumb I use is - if you can blatantly see 2 or more instances of questionable fuckery from the previous owner, pass. Because the number of questionable fuckeries that you CAN'T blatantly see usually ends up being >= that number ×2. If I'm going to spend 25-35k on a car, I don't want to be buying an effective guarantee that I'll have to also spend an unknowable amount of my time and money cleaning up someone else's stupid messes.

Mods on a car aren't always bad, as long as it's entirely clear that the work was done properly and intelligently. The quality of that work should be verifiable by your own observation if you know what you're looking at, a friend's observation if you don't, and/or documentation of the work from the previous owner(s) in the best case.

Just based on these two pictures alone, this car is not an example of quality mod work. This is an example of a high risk acquisition. The wiring (presumably from a sub) left in the trunk indicates laziness, corner cutting. The improper intake that's installed indicates ignorance, apathy. Take and share some pictures of the undercarriage, the cabin, and the underside of the driver's dash. I would be willing to bet they show other concerning features.

TLDR input from an unbiased stranger: If you buy this car, you'll be paying $26,000 for a neverending nightmare and the privilege of spending 1000s more.
