I built this because I got it wrong first
I'm not a mechanic. I'm someone who buys used cars off Facebook Marketplace, and I learned this the expensive way.
In 2021 I paid $4,000 for a 1999 Lexus LS400 showing only 50,000 miles. That number should have stopped me — I now think the odometer had been rolled back. I didn't research the seller. I didn't get a pre-purchase inspection. Over the next 30,000 miles I put in suspension bushings, spark plugs, and about $1,500 on a cooling system whose hoses were cracked and leaking from every joint. Then it threw a rod. I sold it with a blown engine for $500.
A mechanic looking at that car for an hour would have told me most of it.
So on the next one I did it properly: research the platform first, check the year-specific failure points, read what the listing wasn't saying, and inspect before paying. That was a 2011 Prius from an elderly couple moving into a retirement home — it even carried a transferable third-party warranty. I drove it almost four years and sold it when I needed a truck. The truck, a 2010 Tundra, came from a dealer with inspection records I could actually read.
Same buyer. Same kind of listings. The only thing that changed was doing the homework first — and that homework is exactly what BuyerAware does for you.
