Who sells a heat exchanger for the SL600 these days?
Most of the companies that sells these went out of business, ebay has nothing, locally craig's list has nothing...anyone want to point me in the right direction? Car is stupid fast when I first drive, after 20-30 minutes it feels like an SL500. I'm looking for a good HE and upgrade the pump in the process.

Is your pump working?
There is no good bolt-on upgrade that I've seen. Some members have fitted the cooling system from newer M279 V12 cars, which helps massively. One guy with an SL had custom radiators made for all three openings, center and both sides.
In general, the stock system is sufficient for stock power with a working pump. If your power drops off that badly, i'd wager your pump is bad or the system is full of air.

What's dumb is that this car will warn me if my license plate light is out, yet doesn't have a warning for the intercooler pump. I have no idea if it works or not, and i know how troublesome it is to bleed air out of it when changing to a new one so that's why i haven't touched it yet.
I want a larger heat exchanger for aesthetic reasons too, i like seeing cars with a big intercooler in the front, looks aggressive.

Yeah i saw your thread, unfortunately i'm too lazy to do that, kudos to you though. I just want a mean looking intercooler in the front like my Supra. Would a heat exchanger from an SL55 work? They're both water to air correct?

I'm not positive, but I think the SL55 & SL65 use the same heat exchanger.
An alternative would be to adapt the current S65 HE , which has a large area. Pmercury did that here, he thought it worked very well:
