I am 100% satisfied with my Compass. I did my research and found the appropriate vehicle for what I wanted to do with it. I think the regrets come from people who didn't do their homework, so the regret is the fault of the owner, not the Compass.
Lackluster performance - It's a 4 cylinder, 180 hp suv. Duh. It's not going to pull your camper.... But, for a 4 cylinder suv, it's got decent power. It will climb over a mountain (trust me, I do it almost every weekend). I don't need a v8, so I didn't get one.
Feeble accel and road noise - 4 CYLINDER SUV! It's not going to be a racecar. But, my Compass gets up and goes as well as I would expect a 4 cyl suv to. I don't have any road noise, so I'm not sure what others are hearing. I bought my Compass knowing I was going to lift it and put knobby tires on, so I expected there to be road noise. My Compass is super quiet even with those mods.
Driver's seat can't be raised - I'm only 5'5" and the Compass fits me like a glass slipper. I can see over the dash and I consider it quite spacious. If I was 6'10" I wouldn't buy a Compass. I also wouldn't buy a Ferrari.... Does that mean Ferraris are bad?
Overall, I love my compass. It's much more comfortable than a Wrangler. Something I can take my girl out to dinner in and not feel like I'm putting her into a mud truck with 35" tires. My compass can and has done any trail a v8 Grand Cherokee could do, but I still get over 20 mpg. I don't need to tow anything, so a bigger engine isn't needed. I don't plan on drag racing anyone, so the acceleration is good enough for me. And the interior has the Jeep utilitarian feel, but that's why its a jeep and not a Lexus.
Also, I love underdogs. I build motorcycles and love taking an old grandpa bike and turning it into a baddass ripper. Yeah, you can go buy a badass Harley off the showroom floor, but where's the fun in that? The Compass is the little Jeep that could. Yeah, it didn't over impress me when it was stock, but I saw the potential it had. Now I've added what I wanted and subtracted what I didn't and it's like no other Compass I've seen on the road and I love it. If the Compass doesn't meet your standards, don't buy it. Simple as that. Compass on friends!
