Of the cars we have currently, I've had the Jeep for 15 years, but I've hardly driven it for the last 6 or so. It needs a lot, but I also can't quite bring myself to get rid of it. I've always liked it since I bought it, but I'm not sure I've ever been totally in love. It's been a good platform to tinker with though and it's versatile.
The E38 I bought mostly because I'd always wanted one and it seemed like a reasonable enough thing to buy. When I first bought it I liked it, but I think I like it more now than I did then. After a few very minor mods, it's just all around pleasant to drive, and it's been spectacularly useful. I can't think of anything I've ever wished it could do that it hasn't done. It's big, it's comfy, but it doesn't drive like a huge car, the handling is well balanced, it has tons of grip, etc.
SWMBO's 05 Camry came from family on my side, so I've known the car since it was brand new (in fact, it was the first car I ever drove). It's always been exactly what it says on the box, as in "this is a car". It fits plenty of stuff and it's not underpowered (V6). It rides fairly well and it doesn't handle particularly badly (but also nothing impressive). On the other hand, if you try to throw it around, it becomes very clear that the suspension is too soft. And the steering feel is awful, as is the amount of travel the brake pedal has always had. The car has held up spectacularly well (it's at 311k and counting with nothing more than maintenance, engine is still very healthy with negligible oil consumption, maybe 1/8 quart in 5k miles). The transmission feels relatively terrible (shift programming is mediocre at best, it has noticeable shift flare under power, etc.) but it has felt the same forever, so it's just the nature of the beast. It gets reasonable, but not impressive fuel economy as well. The difference in highway MPG compared to the BMW is smaller than I'd expect for an engine with 2/3 the displacement in a smaller car that's nearly 1000 lbs lighter. In the end, I kinda like and respect the thing, but I have no real love for it.
On the other hand, there's the 09 Prius that SWMBO had prior to the Camry. I hated that car with a passion. It was generally unpleasant and annoying to work on in every possible way, it ate front wheel bearings like candy (one good pothole and one is grinding within days). I changed those bearings twice in 40k miles. The steering feel was even worse than the Camry, it was godawful slow (and took forever to get to full power when you put your foot in it). Handling was acceptable but unimpressive. The driving position made it feel extremely tall (even though it wasn't), and so many things about how it drove felt half-baked, as if the engineers got to 80% by the end of Friday and just moved onto the next thing on Monday. Especially how the regen and friction brakes interfaced. Things like regen just dropping out suddenly at 8 mph as you came to a stop, throwing off your intended stop point unless you pushed harder on the pedal. And regen not coming on smoothly, so if the car wasn't in "B" mode, braking lightly but suddenly for a corner meant you got exactly what you asked for, followed a half-second later by the car slamming into full regen. There was no way to disable the traction control on it either, and contrary to what you'd expect for traction control in a hybrid with 2 non-driven wheels for speed reference, the traction control was every bit as bad as a mid-90s GM with a massive power cut from any hint of wheelspin.
