I remember the first time I considered buying a used Montero Sport - that moment when you're standing in a dealership parking lot, staring at this rugged SUV that promises adventure, yet wondering what secrets its previous owner might be hiding. Let me tell you, after helping numerous friends navigate the used car market and making my own share of mistakes, I've learned there are seven crucial checks that can save you from a financial nightmare and help you find that perfect SUV.
Starting with the transmission might sound obvious, but you'd be shocked how many people skip the most basic check. I always take the Montero Sport for at least a 30-minute test drive that includes various road conditions. Listen carefully when shifting between gears - any hesitation, jerking, or unusual noises between 40-60 mph should raise red flags. The automatic transmission in these models typically needs fluid changes every 60,000 miles, and if the current owner can't provide maintenance records, assume the worst. I once test-drove a 2016 model where the transmission shuddered during acceleration, and the seller casually mentioned it "just needed some fluid." That vehicle ended up needing a $4,200 transmission replacement.
Now let's talk about the engine - the heart of your potential adventure machine. Pop the hood and look for any signs of oil leaks around the valve cover gasket and oil pan. Start the engine cold and listen for timing chain rattle, which is a common issue in Montero Sports with over 80,000 miles. Check the exhaust smoke color - blue indicates oil burning, white could mean coolant issues, and black suggests fuel system problems. Personally, I'd walk away from any Montero Sport blowing blue smoke, as that likely means expensive engine work. The 4N15 diesel engine in newer models is generally reliable, but turbocharger failures around the 100,000-mile mark aren't uncommon and can set you back $2,500-$3,500.
The suspension system deserves your undivided attention, especially if you're planning to take your Montero Sport off-road. Bring a flashlight and inspect the shock absorbers for oil leaks. Push down firmly on each corner of the vehicle - if it bounces more than twice, those shocks are likely worn out. Listen for clunking noises when driving over bumps, which could indicate worn bushings or ball joints. I've found that about 60% of used Montero Sports I've inspected needed some suspension work, typically costing $800-$1,200 depending on what's required.
Electrical systems in modern SUVs can be nightmares, and the Montero Sport is no exception. Test every single button, switch, and feature - including the often-overlooked 4WD system. Cycle through all transfer case modes and verify engagement. Check all power windows, mirrors, and the infotainment system. I once nearly bought a Montero Sport where the previous owner had installed cheap aftermarket electronics that caused intermittent electrical issues - the repair quotes came in around $1,800 to fix everything properly.
Rust inspection is absolutely critical, particularly if you're in coastal areas or regions that use road salt. Don't just glance at the surface - get underneath with a flashlight and check the frame rails, suspension mounting points, and the underside of the doors. Surface rust is one thing, but structural rust is a deal-breaker. I recall checking a 2014 model that looked pristine until I crawled underneath and found the frame had significant corrosion - that SUV would have failed safety inspection in six months.
The interior tells you how the previous owner treated the vehicle. Check for unusual wear patterns on the driver's seat, steering wheel, and pedals that might indicate much higher mileage than shown. Test the air conditioning thoroughly - it should blow cold air within minutes of starting the engine. Replacement compressors for these models can cost $600-$900 installed. Look for water stains on headliners or carpets that might indicate leaky sunroof drains or windshield seals.
Finally, never skip the professional inspection. I always budget $150-$200 for a thorough check by a trusted mechanic who specializes in Mitsubishi vehicles. They can spot issues the average buyer would miss and often save you thousands in future repairs. The peace of mind is worth every penny. I learned this lesson the hard way when I skipped the inspection on my first used car purchase - let's just say that "bargain" ended up costing me $3,000 in unexpected repairs within the first year.
Finding the right used Montero Sport requires patience and thorough inspection, but when you find that well-maintained specimen, you're getting one of the most capable and reliable SUVs on the market. Take your time, follow these seven checks religiously, and you'll likely end up with a vehicle that'll serve you faithfully for years of adventures to come. Trust me, doing your homework upfront means you won't be standing there six months later looking at a massive repair bill and thinking, "No way," like that poor soul I met at the repair shop last year who bought a Montero Sport without proper inspection.
