Thats how I was, but when I came to buy a 313 zed, they were so rare, only 2 were for sale within 100 miles of my house and both of those were at dealers so I didnt have much choice! Things may have changed now and so the OP may find a few more available 2nd hand.
Id also look at Nissan Approved Used Cars, you may find one there.
Yeah there isn't many on PH at the moment is there? Weird.... OP - just stay clear of S20004U!
