I'm an ignorant jackass?
Pot/kettle. You spew bad information and try to insult me by calling me names. What are you 12? I mean my 5 year old has better lines than these.
"Things that are stupid"? I mean, seriously.... Anyone that has at least half a brain would research some before they invest in equipment. The fact that you are unaware that there are manual jack alternatives, air is NOT required and the fact that the cost of said units is somewhat reasonable tells the simple tale of your general knowledge on this subject. I base my assessment of you opening your "Jiffy Lube" on this alone. I mean, after you overspend on air to drive your high cost equipment, your oil change price would be extremely high so therefore you surely would go out of business quickly. Simple. (Not to mention most "Jiffy Lube" places don't have drive on 4 post lifts. They typically have open pit bays and small lifts. It's not like they'll be pulling a transmission anyway. Open bay for an oil change, small lift for a quick tire rotation.)
