Mike, what might be enticing today will more than likely not be so in the near future. We tried that route a few years back with Monroe and to be considerate they were much worse than what I thought the old Koni's were. Going around a curve was quite a lean. 1 year later we put on new Koni's and did not like that I second guessed myself and it cost me for my being a spend thrift. Cost me to the value of $600.00 more than if I just bit the bullet and put on Koni,s.
I have a used set, with 36,000 miles, of Bilsteins that I replaced on my 2004 marquis with new Koni,s. You or any else can have for the shipping if you want them. Check to see if they fit. They still work and I only did not like the ride after I had the Koni,s so I went right back to the Koni,s. We do around 15,000 a year now.
