I was just joking about replacing the engine. I was just being facetious and making jokes about the labor time.

I know all the BAT auction action seems to happen right at the end, but I'm surprised that it's at "only" $10k with about an hour left.

There is also the carbon build up issue that can occur in the cylinder heads, but you usually have a code presenting itself when that happens unless the person has altered the software to hide it.

At 137k miles I'm thinking no more than $15k at most.

Feces fish? There's no room for that on the internet!

I really wish I had bought one when I got the e55, there was a 36,000 mile one in red on the same lot for about the same money. What a car.

I'm surprised it took until the second page for this to pop up. Turner Motorsport has done their damndest to keep the price of used E39 M5s low with that page.

My car pops that code a couple of times a year. I turn it back off, it's happy.

The carbon buildup doesn't actually affect performance... it's mostly an emissions thing. The best thing to do is to get a tune that completely removes the whole secondary air system. Then you can remove the stupid secondary air pump and all the associated piping and just install the SAI blockoff plates. Weight reduction + less clutter under the hood + it's the cheapest solution = win/win.

Also, you can minimize carbon buildup by beating the crap out of the engine. A redline a day keeps the carbon away!

It's actually illegal to leave an on-ramp at less than triple digit speeds in an M5.

Yeah? Good to know. Appreciate the info. I'm not one to spread Internet scares necessarily, but I could never find anything I trusted that confirmed it doesn't affect the car's performance.

$13750, final price. Hm, gonna take a look around and see if I can find one of these. I had the 540i Sport and that was a real nice car to drive, but this is something else.

Different car, but how does it rust at the plate area like that?

The low pressure area at the back of the car gloms road salt on the trunklid. Plates may have eroded away the paint, giving it somewhere to start. Remember that the newest of these is about 15 years old now.

I love these and would die to have one, but that whole, space/money thing is getting in the way

That's the last place it rusts, so if you tap it with one of those keychain hammers it will turn into dust.

J/K...what is rust and why would anyone endure it?
