My mechanic of 5 years could not figure out the loud exhaust kind of noise and vibrations. Within 1/2 hour Dale figured it out and fixed it. The broken motor mount my previous mechanic had replaced 2/28/14 was installed backwards. Let me tell you that the sound was horrendous, like a big truck. My 2005 Dodge Neon SXT now purrs. It's just amazing how just an improperly installed motor mount could create such a headache splitting sound. $44.00 for the fix. I now have a new mechanic in Dale. Thank you Dale.
