I sell quite a few inground lifts...dealerships favor them 2:1 since the new designs came out. While the old style had potentials for EPA issues, the new designs don't. The new units are almost exactly the same as a surface lift...electric / hydraulic...and the cylinders are encased in a plastic tub for secondary containment. Absolutely no EPA issues...(although the EPA actually exempted the old style lifts, provided you fixed them as soon as you found them leaking).
Most folks that buy ingrounds do it for one of a few reasons:
1.) Car dealer reasons....A. technician efficiency (an twin post inground is easier to work around B. Service center look (Dealer wants his building to look the best to win awards, etc.) C. Service manager wants to be able to view employees at work (two post surface lifts add "clutter" and make it difficult to supervise techs) D. More service bays in same amount of space...(an inground bay only requires 10' wide of space...a surface lift is 12' minimum..2' x 10 bays is two additional bays with average revenue of $90,000 per bay)
2.) Independent shops typically use an inground due to space requirements...it's very difficult to get surface lifts in some facilities, especially if they have always had ingrounds...working space comes at a premium price.
3.) Homeowners....actually...I haven't quite figured this out yet...but we have sold a few...I would guess the space utilization and look apply to ya'all...and if you're working out of your house...that $90K per bay would be a nice side job...LOL
