  Note that when the mechanic test-drives your car they have to drive
conservatively and sedately - because if they get in an accident or
break something on the car they'll get fired.  One dealer****p had an
insurance policy where they aren't allowed to take a customer car on
the freeway.

  You really need the mechanic to get in the passenger seat and YOU
drive THEM on the test drive, you know how and where to reproduce the
problem much better than they would - or could.

  I re****ted a huge delay in the 2-3 up****ft with a slam as third
engaged that threatened to snap an axle or U-joint, and twice got the
"we took it for a test drive and nothing's wrong."  Brand new van.

  Third time, I took the mechanic out for the test drive and
"reproduced the problem dynamically" on the freeway at 'medium'
intensity.  Reminded him I'd been babying it by feathering the
throttle on up****fts for 5,000 miles, and asked if he wanted me to go
full throttle and break it - Got a brand new transmission.
