I didn't use to like the 99+ Trans Ams, but I have to admit they've grown on me with the passage of time. I saw a yellow/black WS6 on Market St. in San Francisco that sounded SICK. People on the sidewalks were getting startled when he would rev the engine.
My all-time favorite TA though is the 87-92 GTA with the 5.7 liter (Dwight's car on The Office; my aunt had one also). A LSx swap into that would be SWEET in my humble opinion.
The washer fluid is NOT fine!
