O'Fallon Auto Repair

The Fast & Furious franchise has given us two decades of high-octane action, family drama (because nothing says "family" like stealing vaults with muscle cars), and, of course, some of the most ridiculous car stunts ever put on film. As an auto shop in O'Fallon, Missouri, we at Hillside Auto Repair have a deep appreciation for cars—both in movies and in real life. So, let’s break down what these films got right (sort of) and what had us laughing harder than a Honda Civic trying to outrun a submarine. What Fast & Furious Got (Kinda) Right1. Nitro Does Give You a Boost… But Not Like That The movies love their NOS (nitrous oxide) moments—hit the button, and suddenly your car goes from 60 to 200 mph in half a second.

Few things are more frustrating—or dangerous—than watching your temperature gauge climb into the red while you're stuck in O’Fallon traffic. Overheating can leave you stranded on I-64 or Highway K, turning a simple commute into a sweaty, stressful ordeal. But why does it happen, and how can you prevent it? Let’s break it down.

Buying a used car in O'Fallon, Missouri, can feel like navigating a minefield—especially if you’re not sure what to look for. A shiny exterior and a smooth sales pitch might hide costly issues lurking beneath the surface. But fear not! With the right approach, you can test drive a used car like a seasoned detective, uncovering potential problems before they become your problems. Step 1: The Pre-Drive Investigation Before you even turn the key, inspect the car like a pro: Check the Exterior: Look for uneven panel gaps, mismatched paint (signs of past accidents), or rust around the wheel wells. Peek Under the Hood: Look for leaks, corroded battery terminals, or worn belts. A musty smell? Could be water damage. Inspect the Tires: Uneven wear may mean alignment issues or suspension problems. Step 2: The Test Drive—Listen, Feel, and Observe A test drive isn’t just about how the car feels—it ... read more
