Actually lasted longer than the company itself!
An auto repair shop in Gdansk, Poland still uses a Commodore 64 to run its operations: a lesson to learn about consumerism!

This C64C used by a small auto repair shop for balancing driveshafts has been working non-stop for over 25 years! And despite surviving a flood it is still going…
The C64C is actually a C64 with the exterior design remodeled in the sleeker style of the Commodore 128 and some chipset upgrades, released in 1987:
The 64C’s modifications are more than skin-deep with new versions of the SID, VIC and I/O chips being deployed — with the core voltage reduced from 12V to 9V.
Models with the C64E board had the graphic symbols printed on the top of the keys, instead of the normal location at the side.
The sound chip (SID) were changed to use the MOS 8580 chip that uses other filter units, that results in “samples” almost being unaudible.
The 64 kB RAM memory went from 8 chips to 2 chips.
Basic and KERNAL went from two separate chips into one 16 kB ROM chip.
The PLA chip and some TTL chips were integrated into a DIL 64-pin chip.
The “252535–01” PLA integrated the color RAM as well into the same chip.
The smaller physical space made it impossible to put in some internal expansions like a floppy-speeder.
