OK, I have a Kwik Lift system now (see pic below with old parts car) it works fine but I have the green light to look for a 4 post lift. I have found the Pro Park 7 at Greg Smith Equipment main feature I like is it runs off of 110v, sure might not be the fastest going up but that is ok. Comes free with casters, jack tray, and three drip trays.
I wouldn't use this to store the car since I don't think I would have enough clearance to raise it all the way up with the garage door open, plus there is support beam and crap that would keep me from moving the lift closer to the back of my garage.
I would use this for work on the 914 but it would be nice not to have lay on my back to change oil & stuff in the truck or wife's car. I wouldn't be able to lift either of them high enough to stand under them but I could us my rolling stool.
Another thing I was looking at is the PRO 6MR lift I know someone here has this or something close to it. I'm just a little concerned about the stability of this lift but if you watch the video they show it lifting a full size truck. So I'm looking for input. The 4 post is $1,895 plus shipping and the 6MR is $1,295 plus shipping. I could pick these up since Indy is only a couple hour drive and save on shipping
