    Our Chrysler has been in our family for more than 9 years and it only has 59,000 miles. Probably because it was just a grocery getter, not a commuter.

    Looks more like a toned down Focus ST crossover to me.

    Yeah, I know. That's why the current gen Escape has cues from the Focus and Fiesta.

    Not even sure you could call this one a beater. It's...dare I say, mint? But I paid a beater price for it. $2700.
    It's an 07 Mercury Mountaineer Premier V8 AWD. Just ticked over 167k miles. I think it has every option besides voice controls for the navigation and a heated windshield.
    It has the 24 valve SOHC 4.6 Modular V8 producing 292hp and 315 ft-lbs, mated to a 6 speed 6R60S transmission. That combination moves this thing pretty well. I timed a 0-60 at 8.0s.


    Power heated leather seats with driver's memory, auto climate control, navigation, automatic headlights. It all works too.
    What doesn't work are the power deployable running boards. When I got it they were both inop and stuck deployed. I took the driver's side off to try and diagnose why it isn't working but I'm not having much luck.
    The most glaring problems are an exhaust leak, and a strange issue with the torque converter where it will constantly lock and unlock when you're cruising 30-50mph. It's a common problem but no one seems to know what causes it.
    The exhaust leak is a hole in the muffler. I ordered a new one. I can't stand exhaust leaks.

    Interesting vehicle. Certainly a step-up from the Crown Vic :p

    there's an old 80s Cadillac next door that they tried to sell for 1500, I would have looked at it but a V8 land yacht probably isn't very practical for me right now, I already have the bronco and once I have income I'm dumping money into the trans am to get it roadworthy in 2 years (just repair body and mechanics), both are large, comfortable vehicles (they dont make seats like they used to) with lots of space inside and terrible fuel economy :p

    It is an interesting vehicle. That's how it piqued my interest. Basically an AWD Explorer with a 3 valve 4.6 modular and a 6 speed? Color me intrigued.
    I was also fascinated by all the features as I looked into them. Heated seats, deployable running boards, touch screen navigation, automatic climate control, a sound system with a dedicated sub. A lot for the price.
    A problem I forgot to mention with it, though, is a persistent P0420 code. That's bank 1 catalytic converter inefficiency. I've looked at the o2 voltage OBDII data and it seems as though the bank 1 cat is bad and it's not an oxygen sensor or wiring problem. It's also getting a few mpg worse mileage than it should be, and the fuel trims are suspiciously high, particularly bank 1. I would think its the cat messing with the fuel metering on that side somehow, but it doesn't feel down on power and the 0-60 is 8s, the same as healthy low mileage ones, so I'm not inclined to think it's clogged. Don't see why an inefficient catalyst would mess with fuel metering, unless these newfangled cars also consider the downstream o2 sensors in the equation.
    It also has the feeling of a wheel hub bearing beginning to go somewhere.
    I actually didn't come to this from a Crown Vic. I came to it from my 1997 Yukon 5.7. It has been the main focus for the last two years, with Crown Vics mostly serving as cheap, fun, accessible transportation while the Yukon has been in various states of disrepair. I sold my last vic in the fall and I've been dailying it since and its been reliable.

    There it is 2 years ago, standing proudly in the dirt on the maiden voyage after I bought it with a bad transmission and rebuilt it myself. I'd since taken the brush guard off, I decided it was cumbersome. Literally in the sense that it weighed well over 100lbs and weighed down the front of the truck, and figuratively in the sense of it looking like some sort of restraint on the fascia. Anyhow, a few weeks ago the transmission suddenly completely shit out in the middle of nowhere a short 10k miles since my rebuild, and I'm tired of fooling with the thing. The Mountaineer is the replacement.

    Also possible that the O2 sensor is damaged. You'd need an oscilloscope to check it properly under all conditions not just a multimeter/obd at idle. Just been through that fiasco on the Subaru. Exhaust leaks can also cause this.

    Get the exhaust leak fixed first, see if that fixes it, if it's a pre cat leak that can fuck with the pre car reading and in turn impact metering.

    Post cat sensors are used for long term tuning too. So if the error has been there long enough, they can indeed trigger fuelling issues.

    Subaru is still experiencing some kinda issue but the next best point of investigation requires a bit of kit we don't have available spare for a long term loan at work and the issue is so non reproducible that there is no guarantee that setting it up for an hour is going to log anything
    --- Post updated ---
    The sheer amount of data I've collected from this car has been useful for filling up our library of reference waveforms though. The O2 sensor is one we didn't have data for on file, now we do. Same for the MAP.

    But it's leaning out every now and then :/ not often and only briefly. We may just change the fuel filters as they're maintenance items and just blindly hope that they were clogging

    The front end reminds me of early 2000s European economy cars :p

    Still a very attractive vehicle though

    I feel this dramatically improves the styling.

    BMW, Mercedes, and VW are all in hot water again. This time over market collusion. Interestingly, Mercedes whistle blew the collusion arrangements to the authorities in the hope that they will get out without facing penalties. If they succeede in that plan, that's some pretty ingenious back stabbing of their main competitors.

    The European Union has the ability to fine each company up to 10% of their worldwide turnover in response to this. Of course, they also have the option of doing nothing more than a token gesture. But they have stated that they are investigating and belive that illegal activities occurred.

    All I take from this is that Mercedes are hypocritical, backstabbing, conniving, snitches.

    Yeah, I agree. But at the same time, if your partaking in illegal practices to gain an unfair market advantage, you can't really complain when someone else plays dirty too for the same reasons.

    Those companies are pretty dominant in Europe, and when they make pacts with the intent of manipulating the market, it causes all of the other brands to suffer.

    Personally I really like seeing a diverse car market with lots of brands all doing interesting and unique stuff, and that doesn't happen when VW owns half the companies and is colluding with the other big ones.

    Last night taught me the beauty that is power to weight ratio.

    All I know if that there was a traffic light and a V8 Audi, and I never saw them again.
