Chip, this is not a very active list, but I hope you get some responses anyway.
I coordinate a benchmarking program for the Center for Leadership, Innovation and Research in EMS. We discovered about a decade ago that at about 150,000 miles the cost to repair an ambulance exceeds the capital costs to replace it. Have not done a specific updated analysis since then. The participants in that group are all full-service providers, so I’m also interested to hear how that might compare to a what a predominantly transfer service would experience.

I look at a couple of items to determine what vehicles to retire. Keep in mind that we have a fleet of 63 ambulances and we retire 3 or 4 every quarter to stay ahead of the curve, if you will.
I take a look at 6 month and 12 month old data. I start with the highest mileage group of 5 or 6 trucks, determine how often they were in the shop and what the cost was for each repair over the 6 and 12 months. Then I take the mileage driven over that time period and come up with the cost per mile. Since we spend far more money on PM services than repairs, I remove the costs of service and just concentrate on repairs.
I also factor in the year of the truck and look at whether it's been a problem child.
After a period of time you can predict certain major repairs that me be looming based on historical data fleet wide. For example, I may have a low cost per mile on a high mileage truck but still has it's original transmission. I can confidently say that that truck will probably need a $3,000 transmission with in the next cycle of retirees, so it MAY be retired.
There are much more qualified people out there that have better systems and formulas, but this low tech system works for us.
