Sounds about right but when you put it that way, it's pretty dang expensive. If my numbers are right, the $40K in depreciation the previous owner on my 2012 took works out to about $18.26 a day over 6 years, not including any repairs and maintenance they had done. It was probably worse than that because I'm sure they didn't trade it in for the same price I paid for it.
We're at 15 years for the 2007's and 9 years for the 2013's. Hopefully we'll have decent parts availability for the next decade anyway. It raises a good point though: are there some parts that we should stockpile if we want to keep them for years to come? As for how long I'll want (or be able to) wrench on my cars, that's a good question. No idea. I should probably set aside some money for when I can't though.
Well, on the other hand, had I bought a newer K2 with less mileage, there would still have been money spent on maintenance, accessories and some tools, and maybe a condenser and transmission by now! I would probably only about now have to spend more on repairs.
I saved the old lower control arms to be rebushed and the old brake calipers and hoses. Back in the day when I had 5 Buicks, I used a large file box with 27 drawers to store parts in, interior parts, O2 sensors, etc. A couple of years ago I came across another one of those drawers and snatched it up and am doing the same thing again. Julia has the Sierra and Jaime will soon have one as well, all 900s. Plus, my wife may add one to the fleet. Either way, we'll start accumulating parts. I saved the old door handles and am going to pick up complete new regular and tow mirrors and new exterior door handles.
In the coming months I'll get that 14-Bolt axle refurbished and stuffed underneath and then save the old control arms to be rebushed as well. Guess I'll hang onto the 8.6 axle for barter or parts if we have room to store it.
Haven't had to replace the serpentine belt, tensioner or any of the accessories yet. Am going to put an alternator and fuel pump assembly on the shelf, along with new tank straps and such for that eventuality. Will try and be proactive.
They took asbestos out of the brakes and now they are removing copper too. The part numbers that I used for my brake jobs have been superseded it seems. Have to do more research on that end.
Have to find my Mitchell crash book and order up any remaining interior parts too. Kids keep breaking the finish panel on the right passenger 2nd row seat, been through 5 of them at $30 a pop! Covers for the seat tracks in the back were missing when I bought it, want those too.
Well, you get the idea, ramblings over for now!
