Okay, so my buddy just pulled off the most insane used car deal I've ever heard of – copping a 2021 Tesla with 90,000 miles for a mind-blowing $6.7K! Naturally, he's been 'flexing' hard, and it got me thinking: how do you even verify a deal that sounds too good to be true, and what should you look for if you ever stumble upon something similar? First off, when you see a price like $6.7K for a 2021 Tesla, your alarm bells should be ringing. But my friend actually did his homework. The absolute top priority for any high-mileage used EV, especially a Tesla with 90K miles, is the battery health. This isn't just about range, but also about the potential cost of replacement down the line, which can be staggering. He insisted on a detailed battery health report – some third-party apps can give you a decent estimate of current capacity compared to new. Ask about the previous owner's charging habits: did they mostly supercharge? Did they frequently charge to 100% or let it drop to near zero? These factors can impact battery longevity. Beyond the battery, a thorough pre-purchase inspection is non-negotiable. My buddy took the car to an independent Tesla specialist. They checked the motors for any unusual noises or vibrations, especially under acceleration and deceleration. Suspension components are another big one; 90,000 miles can take a toll, so look for worn bushings, shocks, or struts. Don't forget the obvious: tires, brakes, and the charging port itself. Make sure all the doors, windows, and the trunk/frunk operate smoothly. Inside, inspect the infotainment screen for dead pixels or responsiveness issues. Test out all the Autopilot features (if equipped) and make sure sensors are clean and functional. Check for excessive wear on seats, steering wheel, and pedals. With a 2021 model, software updates are still very much a thing, so ensure it’s not running ancient firmware. Another crucial step is asking for the full-service history. Has it been regularly maintained? Were there any significant repairs? Was it involved in any accidents? A clean vehicle history report is a must, but also follow up on any red flags. A deal this good might hide a salvage title or undisclosed damage. Finally, consider the long-term cost of ownership. While $6.7K is an incredible entry price, remember that Tesla parts and service can be pricier than conventional cars. Factor in insurance costs, which can be higher for Teslas. My buddy knows he might be looking at some out-of-warranty repairs soon, but for the initial saving, he felt it was worth the calculated risk. Finding a deal like a 2021 Tesla for $6.7K with 90,000 miles is rare, but it shows that with patience, diligence, and a bit of luck, these gems do exist. Just be prepared to investigate thoroughly to ensure you're not inheriting someone else's problems!
