I have a PRO-6MR from Direct-Lift and I LOVE it!!! It is so perfect for working on a 914 or 911. I have even lifted my 1997 Range Rover HSE with it!
These lifts are not so good for a front-engined rear wheel drive car, but IDEAL for 914 and 911s.
Make sure you get the "truck adapters" with it. I never lift a 914 without those in place and some distributors charge extra for those.
I wouldnt work on anything without it. I could never go back.
Make sure you get a quote INCLUDING the shipping, because the shipping can be very expensive.
