20 year old BMW E46... Bit of rust - Asking for trouble?
Discussion
Hello all
I'm looking at buying an E46 which is in mechanically excellent condition and otherwise in very good condition
However, there is some rust coming up in the rear quarter panel... Is this just surface rust or is it indicative of something going on underneath? Am I asking for trouble?
Is it an easy/simple fix or better to not risk it and walk away?
I've not dabbled with older/classic cars before so this is the first time i'm coming across this, so I wanted to get people's thoughts!
Thanks

It's not a problem on the front wings as you can buy pattern parts on Ebay as they are only bolted on.
Rears are much more of a problem but that doesn't look as bad as most E46s I've seen, which is one of the reasons I moved on to an E90!
If you really like the car and are getting it for a good price then go for it, although it would be worth getting it sorted before it gets any worse.

How did you find your E46 to own?Rears are much more of a problem but that doesn't look as bad as most E46s I've seen, which is one of the reasons I moved on to an E90!

The one i'm looking at is 70k miles and lovely otherwise

Mine was a manual 325ti Compact I bought on 80K miles in December 2014. Within a few months it needed a cooling system refresh because the bottom of the radiator was bent like a banana! That cost nearly £500 as it included an expansion tank and cap, temperature sensor, and auxiliary drive belt as that was starting to break up. Then in November 2016 at 95K miles I had to have a split high pressure PAS pipe replaced for just over £300. Costs quoted included fitting by my Indy.The one i'm looking at is 70k miles and lovely otherwise
Only other costs were for routine servicing, tyres, etc. I loved how it drove but could see some major costs coming up because everything under the car looked crusty - not surprising really as it spent its early years in Scotland!
If I could have found a good Touring I would have bought it, but it was much easier to find an E91 so I replaced it with a manual 325i that I soon replaced with a 330i. Both good cars, way more refined but not as much fun to throw around.

Oh gosh, sounds like a few bits and bobs then!Only other costs were for routine servicing, tyres, etc. I loved how it drove but could see some major costs coming up because everything under the car looked crusty - not surprising really as it spent its early years in Scotland!

I think the reason I want an E46 is that it still had that original 90s vibe before things got more refined
Although to be honest its mostly nostalgia for me. My Dad had an E38 740i and then later an E39 528i from that era in the late 90s, and I have fond memories of my childhood at that time. My sister later had an E46 coupe (328i SE I believe) in the early 2000s

My 330ci was probably the best car I ve ever owned. They are lovely, easy to work on and maintain and are super classy if left standard.
Thar corrosion wouldn t put me off. It s an easy fix
Yep; I run a standard 330ci as a daily and absolutely love it. Thar corrosion wouldn t put me off. It s an easy fix
When I bought it in 2019 it had just had replacement driveshafts (at around 90k miles).
Since then, apart from routine stuff, I've had a broken rear spring (replaced both) and new rear shockers.
A liitle bit of rust on some wheelarches, but I treat it and paint it as and when necessary.
I woould be concerned on the underneath really, does it have the famous rear subframe mount corrosion issues?
The arch needs to be cut out and replaced with new metal to cure properly, rust converters etc are no good.
Only way to judge is to take it to a body shop but you will pay a lot for paint repairs these days.

TBF I didn't think that was too bad for a car that was 12 years old when I bought it. I think the reason I want an E46 is that it still had that original 90s vibe before things got more refined

And it depreciated less than £600 over the 3+ years I had it so less than £200 a year, whereas the 2007 123d I had before averaged more than £200 a month!
The bonus is that if anything good E46s seem to appreciating. And AFAIK it's only M3s that suffer from boot floor issues.
ETA Maybe it's a shame you missed out.

Ref the RACP, they can all suffer but its mainly M3s., it's down to how hard the car has been driven. The spot welds pull out and crack the RACP and further cracks ensue. I had mine reinforced- the rear brake lines were being done so it all had to come down anyway - but mine was fine.And it depreciated less than £600 over the 3+ years I had it so less than £200 a year, whereas the 2007 123d I had before averaged more than £200 a month!

Too late now, but that rust is nothing! Just a little light surface rust. Could be sorted in minutes.
But you would need to get the front arch liners out and clear all the years of damp mud out.
If those are the original wings, a good indication the rest of the car is likely to be good.
Rear arches are where you need to look - any surface rust there has come from the inside…and get the sill covers off to assess sills. Prob have half a tom of mud in there as well.

This was my 'all-season beater' for about 2 years until the gearbox gave up. Still got half my money back and it had saved me thousands on the fuel difference between super unleaded @ ~27mpg vs diesel @ ~40mpg (and much more suitable for skip runs than a 2-seater coupe).
I priced up doing rust repair, but it would have cost more than the car was worth...and I'd only bought it as a stop-gap because it was cheap.
