my floor jack is a race jack from Pep Boys and it had a nice, wide 4 inch rubber base on it that requires no jack pad insert. I bought it for this reason, and it wasn't expensive...something like $74.
this is dirt cheap!!
here they charge you €150 ($180.54 to be precise)per hour of labour plus oil and bits, it cost around €200 for oil change, they actually charged me €10 to change a bulb last year, it was more expensive than the bulb Doh!!
