I am in the market and read up on what to look/listen for when test driving. The car drives well and the height adjustments works good. No noticeable "clunk" at stop or taking off. One thing I could not get pass is the brake pedal, it feels too soft for a big vehicle. I did notice, with the car off, i pumped the brakes several times and it never stiff up. is this normal?
