2010. Bought new with the extended warranty, which ran out this past summer, I think. I can't think of a single issue with our CLS either. Apart from it eating through rear tires. Especially when I drive the car. Our previous E did have a minor issue caused by me. Years ago I bought an E. It was well into the Chrysler marriage and surprisingly, apart from the crappy AC system compared to a domestic, it was relatively problem free. One of the headlights did develop a weird issue with it momentarily going out after big dips in the road. I now chalk it down to mice eating or nibbling at wires. Honestly, I don't think AC systems in imports are as good as some of the domestic offerings. Nothing will beat the AC in say a Tahoe.
In warranty the most expensive to repair cars I've had were probably an Accord V6 I had, that MS6 which developed problems near the end of the lease (then again I abused the car on roads), and probably our Lexus. Which had some suspension issues that set me back around $600, otherwise outside of warranty it would have been a few thousand. I can't remember if I ever had the engine recall on it checked out if it was even affected. Probably did their due diligence on a major service. I've lucked out with the digitizer which seems to fail or the console just dying. I think these were early 2IS problems, though.
Worst out of warranty expenses? Easily an RX7 I picked up a very long time ago. Generally not a wise idea then and especially not now. Looking back I have to ask myself what the hell I was thinking of. I easily spent more in repairs than I paid for the thing over the time I had. RX7s are reliable so as long as you're willing to realize that their parts operable life needs to be reduced by about 30%, you do a lot of oil changes and pushing the cars (because why not?) makes their life expectancy go down. At the time, I wasn't a stranger to major engine work, whereas I am now because it's become very complex with computers and sensors.
If I had a time machine, I'd go back to then, slap myself and then go buy a third gen Celica liftback or a sweet fourth gen coupe or liftback, possibly the coupe because liftbacks were rare. They were barely 'old' then. I think either of these cars go for a premium now with the tuners and those people who do drifting. I had a thing for cars with popups then. I could pretend I was aiming canons at bad drivers.
Never got to own or drive a Z31. And by the time I saw enough good Z32s, the 2nd hand market shot up. I guess video games at the time had influenced a lot of people to get into Japanese imports. Before then, they were good value for your money, new or used. Well, except the RX7s.
I'm just not into used anything anymore. Unless it's something unique. Like a mint IS F and not the gutter trash they've been turned into. Or a mint 190. I like 190s. They're one of the hardtacks of European imports. Hardtack is a rock hard bread invented in New England when the Vikings were still alive (not) and it'll last for decades until you need it.

@840quadra owns a sweet 190.
Edit: Crap, sorry. I have a habit of going on tangents.
Right right. Did you ever own either a VW, Volvo or Ford estate?
