In the early 80's I was in the Navy, and traded my POS Mercury Monarch (nee Granada) in on a well-used 1975 Pontiac Firebird with the Poncho V-8. That old 'Bird already had some 70,000 miles on her, and had clocked up 213,000 by the time I traded it in. Went literally coast-to-coast twice during my hitch. Had a blast, made out like a bandit on travel time and pay! Only got one speeding ticket.
It's tied with a little '68 AMC AMX two-seater as the most fun car I ever had. The AMX was quick as a scalded cat up to it's 104MPH top end (AMX's were street legal dragsters basically) but the Firebird was more refined and much faster and more comfortable. I tended to shift both through the gears, nevermind they had auto trannies.
Gosh, I miss those days......
