Just to chime in late, since my company works with parking garages...
New garages are currently being fitted with SUVs in mind where the lower floors have a 10 to 12 foot clearance. Most facilitys charge a premium (up to 20 dollars per day
extra in NYC) to park there.
Most all garages have ballards that show the clearance of the lowest point of the garage on entry...if you hit that on the way in, I would suggest parking elsewhere. As for the Renegage...I scrape most of these on the way in to locations and have the yellow paint on the roof rack to prove it
Personally, I would not suggest a lift if you frequent many garages.
