Question about a lift from craigslist

I am considering buying this front end lift from craigslist but wanted to get some feedback first. The ad reads as follows:

"Not even 9 months old Bilstein 5100 adjustable shock w/ Eibach racing coils paid 599.00 for them"

He is down to $240 for them. The link is below. Is this a good deal and what should a do for the rear? Thanks for the help.

It's a decent lift, will ride kind of rough but to compliment that and if you are on a budget go with an add a leaf in the rear.
