KYB's are great, i have them in my car (older model Corolla). 650-700 is WAY too much for 2 shocks plus fitting. If my memory serves me right, i paid under $200 for all four shocks fitted. Surely there are some other mechanics you can go to? I would recommend suspension specialists as they will get it done faster, faster = less labour costs. Also try to supply the part, so purchase the parts from say Burson's/Repco to save on any mark-up costs mechanics will charge you. cheers
