My first car was a RWD, four cylinder turbo, 5 speed, and could get 30 mpg hwy pretty dang easily.
I could only wish it was one billionth as nice as that one. *I would take a turbo tbird over a mustang any day*
Still the most comfortable car I've ever driven to this day. They can handle awesome too.
Btw the Xr4ti was not just a dressed up mustang. Completely different car. Based on the euro sierra. Only thing they shared was the 2.3 turbo.
edit: that particular tbird has had a supercharged 306 swapped in...I doubt it still gets 30 mpg LOL
