I know various people have thought about this, so having finally bitten the bullet and done it myself, I thought I would post a wee picture of my new 4 post ramp in action.
Happy to supply details and observations/findings from installing it myself if anyone is interested, but the usual "amateur status" health warning applies.
Note that, at this stage, I have only had the courage to raise the car to the first ratchet stop of the safety
It was a nice to find that...
a) the 348, my widest car, could make it onto the ramp without issue
b) the lights all across the glen did not go out when I pushed the "up" button
