I drove mine per the factory instructions. 50-60 mph for the first 500 miles, then around 50-70 mph with bursts to 100 mph for a short sprint. I wait till the rpm's drop from 1200 on startup to 700 rpm's then put the car into reverse to back out of my garage. I do not dog the car. Now with 900 miles on the car, I blew away a souped up Mustang, then slowed down to 60 mph. He must of been embarrassed with his friends in the car, cause he never even tried to catch up to me. I'm 59 years old and I love this car. Hopefully the ticking sound will disappear with more miles on the car. When I have 1500 miles on the car I will take back to dealer for my free oil change and take the print out Venthos listed with the tsb's and recalls. I already took it back for the ign module, showed service mgr seat bolts, he filed paperwork with Chrysler. This is my last new car for life, so any gremlins floating around in the car, I hope are minor ones.
