The 1999-2000 CSVT's have slightly more HP and torque, as well as the nicer "Cobra" type wheels, and slightly bigger tires. I am a new CSVT owner but from what I have read, the transmissions are not super strong. Don't try to shift one like the T-5 in your 88 GT. I have owned a total of 8 Mustangs in my life, they seem almost unbreakable. I would never drive the CSVT as hard as I did my Mustangs.
So far, the Contour is a great daily driver. Plenty of power, engine is smooth as silk, shifts very easily, and gets great fuel economy (which is good because gas will soon be $2.50/gal).
I bought one because the last Mustang I had was a pain getting my 2 kids in and out of. I was not sure if I was going to like the CSVT after owning Mustangs for the past 15 years, but I love it!
Good luck!
