My 70 Cuda just hit the road in April and spun a rod bearing at the end of June with 721 miles on it. I had it back running the end of August and ended up with a total of 1,815 miles on it. My 71 Challenger RT I drive everywhere and put about 2,500 miles year including driving it to the Mopar Nationals. I have owned my 71 Challenger RT since 1989 and have put around 40,000 miles on it. Would drive them more if the weather permited.
