I am 6'5" tall and my 2008 Prius just doesnt have the leg room for tall folks. I needed to extend the seat backward. After reading every forum and visiting serveral body shops and coming up empty....liability issues were cited... I got a quote of $1,400 to modify the front driver seat track. And then, exasperated, I tried one more search and found amazing productfrom Extend My Seat. Extend My Seat Install Guides For under 200.00 and a simple install (less than 30 minutes with one tool.... a 15mm socket wrench) I had another 4 inches of glorioius leg room. Check out the install video above. Note : You do NOT have to remove the seat and dissconnect under seat wiring as suggested in the written instructions. Simply take out the factory bolts and tilt the seat backward and forward as needed to install the new extend brackets. Now I have limo leg room in a Prius! .
