Question Buying an SL55 any advice?

I'm looking into buying 2006 SL55 with pretty low mileage, does anyone have any advice or knowledge of what I should look out for?
thank you

Yes sure, I just bought my first SL55 last month 2003 with 80k miles.

I would say from my research is:
ABC suspension - After checking mine before purchasing I am starting to think I have a very small issue with ride height. Check ride hide before and after a drive and not just parked up.
Soft-close boot - I am still researching if this is a standard feature, but looks like most r230s soft close fails due to an actuator leaking air in the bootlid
Massaging seats - again work on air so check these as the air lines under the seat can leak, so system shutsoff after a few mins
Roof mechanism - ideally also check for leaks or any damp carpet in the boot
ABC service history check for ABC flushing or replacement/services stuts/actuators/valve bodies
Intercooler pump - Again these all seem to fail especially if they are original - Bosch made an upgraded bump which is about £150. Symptoms are loss or power, intermittent power. I had this on mine in the first week
Prop shaft bearing - Mine needed changing as it was knocking from 0mph-15mph from rest

hope that helps

Thank you I really appreciate you taking the time to reply!

I did test drive the car and everything seemed to work properly, the salesman did say it was sitting for a bit and the car battery had low voltage so a few things like the top didn't go down, and a message on the dash saying "stop braking power reduced" but only when the car was parked and off..? I was told it would be taken to the Mercedes dealership to be fixed

2006 Models forward came with the upgraded pump. Otherwise all feedback was spot on in terms of what to look for. If you can, I'd look to buy an 07 (or 08 but they're very rare) as they had improved performance, enhancements to the ABC system, larger diameter wheels and other minor improvements.
