From my experience as an insurance adjuster specializing in total loss vehicles, I’ve seen countless people regret not getting GAP. With your $5,000 down payment on a $30,000 car, you’ll likely be underwater almost immediately after factoring in taxes and fees. If your car depreciates by, say, 20% in the first year, its value would be around $24,000, and you’d still owe close to $23,000 (depending on your loan terms), creating a potential $1,000 gap that GAP insurance would cover.
