Or you can be a total masochist and keep an s85 in your stable for 8+ years.
At least that engine only has like 3 things that can go wrong with it. As far as I know, as long as you do rod bearings straight away, the other two are a maybe and can be addressed if/when they come up. Plus you get to listen to a V10. Personally, the S62 has always been my favorite, but I like having xDrive in my daily, so I really don't have a need for a big rwd sedan as a toy. I'd rather have an S62 in something like an E30 or E46. Maybe someday...

A 2013 will be an N55, so you shouldn't have any turbo problems. As far as I know, those have been pretty damn solid motors, and as such, I want one myself. You'll have to pull the plastic pan off the bottom of the car to be able to see the engine, but just look for evidence of an oil leak around the oil pan, as well as on the passenger side of the engine from the top just under the valve cover. Chances are, if the valve cover tasket is leaking, you'll be able to smell the burning oil once the car is warm. I'd plan on replacing the water pump and thermostat when you have a chance, as a quick look online shows that they commonly fail somewhere between 70k and 100k. On my car, it wasn't too difficult, and buying OE parts from FCPEuro or ECS will cost a lot less than the dealer. I recommend replacing that preventatively only because it's the one thing that can really leave you stranded. An aftermarket charge pipe might also be a good idea at some point, especially if you're planning on putting a tune on it.

I've heard mixed reviews of those generation cars, however nothing but good things about the NA motors from that generation. Uncle has a 128i that's an utter blast on back roads. Friend has a 328xi that runs well (I hate the auto in it though). The N5x motors of that generation were pretty stout. It all depends on who owned it previously.

If you pull the trigger, welcome to the BMW family! I'm a BMWCCA member with an original M-Tech II E30 convertible in my stable. It was my first car in high school and the original love of my life. Currently awaiting a Metric Mechanics M20 motor when funds are available.

Ahh, good ol electric water pump. Once it dies, it's silent and you blow your head gasket because you warped the head :p

Seriously though, I don't think it's worth the hassle unless you have no space for your belt drive.

The N55 is a great motor that suffers from cheap plastics and gaskets. I will echo what meismyname said above. Oil pan gasket from the bottom or oil filter housing gasket from the top are what usually leaks. Coolant expansion tank might leak too. Once you get to tuning (I suggest MHD or BM3 for extra boost, xhp for transmission), you can’t go back to NA motors.

Apparently BMW agreed with you, because they went back to a mechanical water pump on the B58. That being said, I don't know if BMW has ever made a reliable cooling system. I don't remember if the E30 was solid or not, but I'm pretty sure every other generation of 3 series has had cooling system troubles in one form or another.

Yea, my m44 has the same issue. Change water pump, thermostat, and radiator after 100k miles. It's easy enough on my car because I have a ton of space (8in at least) in front of the engine so it's just a matter of sourcing parts cheaply (from the manufacturer seems to be best; my MAF was cheaper to get from Germany from Bosch and my condenser was dirt cheap from the BEHR factory in Fort Worth).

Congrats! Pics or it didn't happen.

Sign up with BMWCCA, as we have great driver education programs. Also, sign up for an HPDE with BMWCCA or NASAproracing.com -- for a driver mod, you might just get hooked! #racingruninedmylife

As far as on-going maintenance, check out Mike Miller's Old School Maintenance Schedule. Mike Miller was the longtime Technical Editor/Director of Roundel BMWCCA's magazine before he retired. I use his schedule on my ///M cars, but cut his intervals in half for the higher-maintenance sXX engines.

Congrats again.

Thanks for the part # it looks like a moderate job from this video with the correct tools and a lift but I'm not so sure it would be this easy with a Jack and stands
He gets alot of leverage in tight places that look like standing is the way to go and laying down couldn't be substituted

Congrats!! Sounds like you got an awesome deal for that M3 335i M. Just to compare, I picked up a 2011 328xi 6-speed manual with 40k miles on it back in 2015 for about $12K and have been loving it ever since. It's my first real sports car so maybe next one I'll try to find an M series.

That's not an M3.
