Can i pay on installment for any car as a student

That's going to be between you and the selling Dealer. Cargurus is an advertising site only. Similar to Craigslist, Facebook Marketplace, etc. If you have good credit a Dealer may be able to get you financing. Most likely with a cosigner. Stay away from those buy here pay here places! The plus side to them is they'll finance anyone. But the down side is you usually have to put a huge downpayment, often half of the price of the vehicle, the vehicles they offer for sale are usually fugitives from the auto auction that are in poor condition. These vehicles wind up at the buy here pay here lot because nobody else wants them! Hope that helps! Jim
