RE: How many miles on your challenger
Just a shade over 2000 miles since mid November. Bought the car to drive all year, including through the Northern IL winters though I do have a beater pick-up for when it is calling for accumulating snow.
Which was working out until the truck decided to leak brake fluid out of the rear system somehow. I can't find any leaks now, filled the master cylinder and bled them and now it seems ok. The result was I did end up driving the Challenger in a 2-4 inch snow storm for a few days with no issues. It handled well with the stock all seasons on 20's.
Right now the challenger is sitting in my driveway covered in the latest 8 inches (and counting) snow dumping we are getting here.
