Just about every car I've ever had was over 100k miles at some point.
1979 Mercedes 240D. Sold it with 186,000 miles on it. Little did I know that car would turn 1,000,000 miles. I've lost track of where it is now. It got about 35 MPG which for a 1979 car is amazing. Slower than frozen snot, but once you got to speed it'd stay there all day until you ran out of fuel. AC ran cold, but took up quite a bit of oomph from the underpowered engine. Very simple to repair. NO electronics on it whatsoever. This car also refused to turn off at times, which was amusing. It was a stick, so you'd just stall it out until you bothered to fix the vacuum leaks. Sometimes I'd just lock the door and let it run with the aircon keeping the car nice and cold while I went in the store.
2004 Infiniti M45 (Nissan Gloria). Bought it new, sold it with 225,000 miles 10 years later to the mechanic at the dealership who always worked on it. I sold it fearing that 10 years of Florida sun and putting it through hell would mean it'd become unreliable. On the last night I had it, I had an emergency call overnight and had to drive 2+ hours to get there. Even doing triple digits, at 224,000 miles, the car was still solid. I had the car modified with extra mufflers to make it near-silent and had twin ACs on it. Even when an AC failed, I still had aircon that was on-par with most rental cars. I also had a fridge and 110v inverter in there. VERY expensive to keep on the road though, more expensive than a Bentley of the same era.
I had a 1994 Q45 which made it to 183,000 miles before I bought the 2004 M45. By the time I traded it in, it definitely needed some work. Antilock brake system failed, SRS/airbag systems failed, and it was on its 3rd(!) transmission and needed a 4th. I absolutely loved the interior, with real leather everywhere...but I was not about to put a 4th transmission in there.
At one point I had a Mercedes 6.9 with >125,000 miles on it. Truly a bank vault on wheels. This is what happens when engineers are allowed to do whatever they want and the bean counters are locked out of the party. Absolutely wonderful. Mine had the "illegal" hydraulic ride adjustment knob. That Q45 felt somewhat like this, but was nowhere near as athletic. These sold for ~$53k in 1979. In today's American pesos, that'd be ~$221,000. Cadillacs were selling from $12k-$18k at the time. This is another car I should have held onto, as they were cheap at the time I got it, but are selling for good money now.
