 I have owned two Windstars; '95 & '97. Bought the '95 used. Engine blew.  Bought a new '99 LX with 4 doors.  Justification was the '99 was "redesigned". I learned "redesigned" does not mean "improved" it just means different. All of the same problems everyone else has had.The pinging started at mile 1 off the dealer lot. Blamed many times on bad gas in the Dallas/Ft. Worth metroplex.  Finally with 74K they replaced intake manifold - on my nickel. What a difference! First time it ran right. Now the tranny problems begin. At 94K traded for used Tahoe.
