Basically, LOL Alky - time to grow up after all these years of doing this. You want to be a baby and 'publicly' call me out, so here we go. I've asked you to keep it to PM but I have some extra time tonight so I'll enjoy taking your little bait.
An s54 lease going to the dealer every 2k-3k miles is not a good thing, my friend.
My car (purchased from the original owner) with the same engine and electronics as your m3 only went to the dealer for the recommended services because there wasn't even a single issue with the car. On top of that, the original owner had the trans and diff fluid at 5k, and did an oil change at 7500 miles (I bought it with 8k). He provided receipts for all of this. I met him, got a good feel for the car and how it was treated along with a detailed inspection, paid for it and drove the car home.
Again, on a minivan, regular 4 door sedan, or truck this is definitely not worth the extra 5-10% cost nor the time... You can get a good idea of its condition based on pictures or relying on a decent dealer. On an expensive sports car, motorcycle, etc with a picky engine that deals with valve adjustments and is extremely sensitive to not being run hard when cold it's just about required.
Go back and reread my posts - I was really and truly only trying to help you with my advice. I wasn't being shitty or trolling or any of it. I know a lot about the engine and setup of your car, and dealing with sports car type crap. All of my advice was with good intent and most if it is pretty well known anyway.
But, this is the norm for you.. Your immediate reaction to advice has always been to turn around and be a complete douchebag to anyone who recommends something other than what you've solidified as correct in your little caveman brain.
No doubt you have some attention to detail and are intelligent and all that, but you could really stand to take a step back and be more self aware - even if just on these forums. At some point you must wonder if maybe, just maybe, allllll of these people who know how you really are might just have some advice that you can learn from? Not just in the garage where you've been trolling for awhile now, but also what's been told to you on a personal level in OT.
In a way I kind of like you, I don't think you're a bad person (actually you seem to be a really good person overall, or at least try to come across that way) and it's great that you stand up for what you think is right.. But the way you approach some things is so screwed up and blind it's kind of sad. Mainly because eventually you'll wake up, unfortunately probably as an old man.
There's no way it's limited to the forums either, it must transfer to your real life.. It probably takes people awhile, but eventually they figure you out.
Again Alky, even here I'm only wanting to wake you up a bit and only mean the best but keep in mind the shit you throw tends to bounce off a wall and hit you in the face
So there you go, I'm done with the topic for the second (and hopefully final) time.
