Hi all,
I've had my slk230 for a while. He's about to arrive at his 250000km and I was wondering if anyone had recommendations on what time of maintenance to do.

I was thinking of changing sparkplugs, all car fluids (including gearbox and compressor), change filters.

I'm also ordering some new Wheels and tires for the car (kinda like a present lol) and doing a full paint job. Will these fit?

Thanks for the help
;)

If you kept it up to date with maintenance schedules, would carry on doing that.

Bigger wheels, just need to be careful it does not trash the ride.

@Dave2302 will have a good idea.

As said above, much depends on previous maintenance history.
Rubber parts deteriorate with age. That covers lots of parts and well worth inspecting all bushes and gaiters.

And congratulations on the mileage. (Over 150K miles for imperialists).

Unfortunately, i don't have the service records. When i got it i just kept on doing the normal maintenance (oil and filters), so i was thinking of doing a big check of everything.

Probably time to renew all fluids that you have not done, brakes, power steering.

Couple of links for other stuff:

Roof

I'd use the buyers inspection guide as a starting point:

Change the roof locking hydraulic cylinder seal, if you haven't already.
High probability of failure, and if it does will ruin a $400 headliner, that is very hard to find replacements.

Larger wheels will reduce ride quality. Heavier wheels will noticeably slow the acceleration.

When I got my lady, I changed everything serviceable even with full service history still changed it all so I knew when it been changed so could reset the schedule.

thank you for the manual. I added the Rear diff as said by Mn car guy.
I've just sent an email to a company there in the US and will be sending my hardtop hydraulics to be rebuilt. actually really cheap

18" Wheels with decent tyres do not ruin ride quality, sure it's a tad harder, but doesn't rattle yer skeleton, and I'm an old git with Arthritis ;)

Normally I'd run Avon ZV7's on all my cars, but due to the Rear Tyre size being unavailable in Avon in the UK, I used Uniroyal Rainsports on mine 255 / 35 x18 rears and 235 / 40 x 18 front's on my V8 R170, sticks well (considering the power to weight), and rides good too, Billies B4 Shocks all round and CLK 500 front springs, stock SLK320 Rear springs, and I've swapped the Spring Pads to tailor the ride height ;)

Time the open and closing of the hardtop, supposed to be about 25 seconds. If significantly longer, the hydraulic pump may be worn out. Could change while addressing hydraulic cylinders.

In my experience of 5 R170 cars, only the roof cylinder seal has ever leaked on 3. And changing the seal with cylinder still plumbed to car is much simpler than complete removal. I now change this seal proactively on every car before it leaks.

Happy Motoring,

One more...
Clean out oil separator on engine air intake system. These clog and allow oil into the intake tract, which is a little messy and can contaminate the mass air flow sensor.
