soflotoyo,
1. The brake job does seems high but unless one has more details it is not fair to judge the price. What does it actually include? Brake shoes, wheel cylinders, master cylinder, assist slave cylinder etc.
2. Hour meter readings at best are only a guide. Hour meters can go bad and be replaced with a new one that starts at 0000 hours. I know a large Toyota dealer in Atlanta that replaces all the hour meters as an SOP when they delivery a reconditioned lift. It is always a good idea when buying a pre-owned (used, reconditioned) lift to ask the dealer for copies of the service history on the unit - they should have it if they had the unit in their rental fleet or if they performed service on the unit. I sold used equipment & would offer the customer copies of the service history as a condition of the sale. Customers liked that.
3. The 7 series Toyota lifts in this class were replaced by the 8 series in 2007. So it is 4 years old - warranty has long expired. Warranties are stated in terms of time & hours & expire which ever one is reached first.
4. I've worked for small & large dealers and it was common practice that an annual PM would be billed out with travel time, standard service labor rates & parts.
To receive a "preferential" rate (meaning no travel time charge & a fixed labor rate for defined PM services,) the PM service had to be performed at least every 90 day interval.
5. Customers have shown me invoices from small independent dealers with a standard service labor rate of $50.00, our labor rates were $75 to $85/hour) & their total invoice cost for a PM would be $325 -$360. The independent dealer cannot buy OEM parts at a good price so they buy a lot of parts from the cheapest source they can find & usually these parts don't last as long - but they fit. Personally, I buy service parts for my vehicles Ford & have found that their prices are real close to the "will fitters" like Auto Zone, PEP Boys, Advanced, O'Reilly's but I have the assurance that I am receiving the parts with current updates from the manufacturer. "Will fitter" parts houses keep selling them until their supply is exhausted.
5. I realize you rarely use the lift at 10 hours per year. This is not a good thing long term. The engine rarely gets to operating temperature which means condensation can build up in the oil pan - condensation will cause sludge built up & acid formation which can attack bearing, seals, etc., axle, transmission seals need to be worked to remain pliable. Condensation can be a big issue in Florida. Play havoc with the LPG fuel system (tar build up), etc - the LPG system uses heat from the engine coolant to better vaporize the fuel coming from the tank.

I am not a Toyota guy, never have been, never will be (I'm retired) but what I have stated here can be applied to any brand you.

Like some one mentioned Linde is great when it comes to brakes but OMG their PM service cost are an arm & a leg - I worked for a Linde dealer..
