Looking at getting a Used Infiniti 2006 or 2007 M35 or M45 and would like to have 1 1/4'' hitch for a bike rack.My current bike rack, Yakima is roof mount, but it is so loud with wind that l stopped using my sunroof.Also, I'd like to keep the lines of such a nice auto undisturbed.

Check out autoanything.com or google m35 ''trailer hitch.''

l do not see a hitch listed for your vehicle with Draw-tite or Curt. One option for you would be to contact a certified welder and have one fabricated for you. You can find the tubing here: http://store.drawtite.com/3006.html That is for a 1 1/4'' x 1 1/4''. l know it probably sounds expensive to have it made, but there are a lot of local welders that have good pricing.
