E46 M3 waterpump is like $350..  the N52 pump is more like $400 but yeah.  I'm hoping mine will last to 150k which is longer than an M20's lasts but it's also 10x more expensive.

We've had them rolling into the shop at 90-100k.
Do the t-stat too. It's all mounted together.

meh. the increased efficiency probably pays for itself at the pump. the whole idea behind the electric waterpump and composite block are pretty cool IMO, even if the pump is possibly flawed (I'm not sure it is, waterpumps don't typically last forever).Comment

E46 would probably be the best choice for her. What would probably be the best idea is to have her test drive a few models to see what one she feels the most.Comment

PS pumps on e90s too. My mom's just blew the PS lines and stuff all over.
On the 90forums they say to change the PS fluid every 30k to prevent this...-Christian

Troo troo.....my only gripe is the people who buy these 2nd hand to have a BMW and come from driving mid level Japanese cars.
"$1000 for a water pump and thermostat!?"
"$600 for a trans service!?"
90% of the people driving these things haven't got a clue about them. They just know they drive a BMW something-or-other.
Also, the N series engine.....watch that drive belt and pulleys! It'll suck the belt into the crankcase should something break or seize up. Seen them wrapped up into the timing chain and up to the cams.1974.5 Jensen Healey : 2003 330i/5Comment

yeah I looked at mine, I think it's been replaced already too. Wifes looks good but I'll replace it early to be sure.Comment

This is the truth. This is why I stopped working at a shop which catered to imports.Troo troo.....my only gripe is the people who buy these 2nd hand to have a BMW and come from driving mid level Japanese cars.

But really, as a DD goes, the e90 is superior to the e46 in many many ways.IG: @Baye30

The first question you should ask is how often she will be driving it and how many miles a year approx.. I had a clean 330ci but realized I put 35k on it in one year. The value of newer bmws starts to drop off exponentially when you approach 200k. So I sold that and got an e28. Putting 35k miles a year on an e28 or e30 won't be such losing investment.Comment

The engine itself is strong, but it has a poorly designed emissions system. At 32k miles it needed a new intake manifold, MAF, valve cover gasket, EGR, EGR cooler, and swirl flaps. They also walnut blasted the head. All because of carbon buildup. Luckily it's under warranty. There were two other 335d's at the dealership for the same problem. Their DDM's are also prone to failure. However, the torque and fuel efficiency is addicting.Comment

150k kilometers or miles? One thing I like about my E90 is it has just over 100k miles on it and it doesn't leak a single drop of fluid. Not like my E30, the Exxon Valdez.. there's still an oil stain in the parking lot at work from it. lol
you do have to take some of these failures with a grain of salt:
- the forums are where people go to complain about problems, not talk about how their car isn't broken.
- people on forums are typically younger, and a lot of them beat the fuck out of their cars
- many of these cars are heavily modified (and not always well, as we know with E30s that have been through 4-5 people).
- they're also cheap bastards, even worse than here IMO. I guess because of their $600/mo payments for a new car, and fixing it all the time or whatever. :pComment

miles and climbing
never had any whines, or groans from the system either. I attribute it to constant flushing the first year I had it. I was under the impression that the res fluid needed to be as clean as the fluid I was pouring in.
many years and miles later, I have yet to add a drop.
The only place I ever leaked from, was the HG of my M20

Any particular reasons? I am honestly curious, I'm not being a smartass. I have contemplated an E90 in place of my E46.1989 325i - 2.7i, Holset H1C, 60lb injectors, whodwho MS-PNP.
