They had a 22 month warranty (why not 24 I don't know). I bought a new D325 back in 1990 and ran a AX.25 BBS & packet node on it 24/7/365. After 20 months’ use I discovered it would not always warm boot and would less often successfully cold boot. The shop determined that “something” was failed on the motherboard. Leading Edge was essentially in failure by that time and it took about a month to find and ship a new board, but after it was replaced I continued on with the machine until early 2000, by which time the machine and it's mission were both technologically obsolete.
Unlike any Macbook it WOULD anchor a good sized boat. It was a huge old workhorse, with 8 slots and 6 bays, and it was stuffed full with 4 MB of RAM plus the optional 100 MB drive and ATI 256 color VGA card, all for a cool $1500 with no monitor.
After retiring it, on a whim I hooked up a drive that had Win95 on it and I'll be darned it took forever, but it loaded.
Yes I remember Leading Edge back then. IIRC they were the same company that manufactured those cheapo Elephant floppy diskettes I used back in 1985.
