I would not worry about the year, and find the T Bird that you like the most, color, mileage, condition, previous care,
rust underside,
and simply how much you like it.
The 2002 has the hydraulic fan. On the 2003 to 2005 the variable valve timing can
become expensive after high mileage. A retired Ford mechanic that worked on retro T Birds told me on the hydraulic fan system
all you had to do was keep the hydraulic fluid full, and make repairs if system started leaking. Air and contaminants in the hydraulic
fluid is what killed the system, and damages the hydraulic actuator. He suggested to change the hydraulic fluid after 50 k miles
just to be on the safe side. Two years ago I bought a new fan assembly, a rebuilt pump, and two actuators just to always have the
parts available.
COPS,
PCM, suspension is an issue on all years. The 2002 shared many components with the 2000-2002 Lincoln LS so there are
many interchangeable
parts. The Jaguar S also shared many
parts. For the instrument panel, the 2002 shares the same instrument
panel as the 2000-2002 Lincoln LS, the instrument panel is two pieces, one piece matches the T Bird panel, the other piece is
different, and there are mega thousands of Lincoln LS cars out there.
The body
parts are common to all year T Birds, and these are what is getting hard to find.
I have two 2002 T Birds and both are original except for the suspension, and
ac compressor on one car, and one
fuel pump. I also
have a spare high mileage 2002 with 129987 miles, and hydraulic fan works fine, and is original.
A friend of mine bought a used 2004 T Bird last year after he rode in mine a few times. It is a little faster than mine, but engine
makes more noise than mine. Honestly my 2002 is faster than I have ever needed, I did not buy it to be a hot rod, bought it
to be a cruiser, which it does very well. In the 19 years I have owned it, I have maybe floored it three times. It goes faster than
I want it to go. My friend has already has a few problems with his 2004, where my 2002 has not had problems. That could
simply due to previous owner may not have cared for the car enough.
So find the year you want, and hopefully it has been taken care of. Either you, or a knowledgeable mechanic need to go over the
car top and bottom to make sure you get a good one.
Good luck.
