So I finally got around to taking my car to the dealer to find out about the violent shaking that happens when I get up around 65 – 70MPH. Here’s the technician’s notes from the bill:

ROAD TEST TO 60 MPH-FRONT END COMPONENTS WORN LOSE, RATTLE, ENGINE KNOCKS, NUMEROUS LEAKS, ETC. RECOMMEND ENGINE $4500.00 TO REPLACE ENGINE.

So, it looks like I’m in the market for a new car. I’m pretty impressed this one lasted as long as it did, it’s 1992 Mercury Sable with 120,200 miles on it.
