    Has anyone upgraded to shorter pulleys at all? Wondering how difficult it might be, & if the benefits balance with the grief & expense??

    I've heard of it done , but if like me you are an owner of the M271 engine (with its cam chain issues ) I would do some googling of that first to see if the pulley upgrade might shorten the life of the cam chain . I have no idea if it would or not , but reading about the cam chain may make you spend your money in that direction first ?

    Ah, well I was going to confirm its a M271,but seeing as that's been done.....It's a fair point, not really looking to do anything that will turn my power plant into shrapnel. That said, I'm at 65k & no issues thus far. Any idea what the life cycle of the chain is??

    About 75k normally :)

    If you have any rattle at startup, it may be an idea to change it preemptively. Much cheaper than doing it after its jumped (if you have symptoms)

    No symptoms as yet, but it'll likely be worth getting in touch with German Automotive (Local, well regarded specialist) & sounding out how much it'll sting me for. I'm quite a big fan of proactive, not reactivate, maintainance. Well, that's what I tell my clients, at any rate.

    My M271 plan is wait until 80k , I'm at 67k at the moment and doing oil and filter changes every 5k . Then I may change the car ? I'm about 2 years from that at my current rate .

    I've no wish to change it yet, given I've only had it 8 or so weeks, but I have seen a 500SL on AutoTrader for around 5k....thinking about taking a punt.

    2004. It's a Cat C, which I've never had any dealings with before, but kinda figure no harm can be done by taking a look.

    Ok so an R230 (which is technically not a 500SL but an SL500 - the 500SL being an earlier generation.
    A r230 requires deep pockets to run. The 500 is equipped with Active Body Control which can easily throw a £3000 or bigger bill. Each front and rear strut is £1200. Then you have the ABC pump, valve blocks, gas spheres and the ever present risk of corroded pipework.
    You also have SBC which at around 100-130k will probably require a new SBC pump. Expect £500-1000 for that too.
    Roof leaks into the boot are common. Water in the boot will kill the PSE (central locking) pump - expect £1000 for that too. You'll also struggle to get better.than 25mpg - 15 in town if you're lucky.

    Now that all said they are lovely cars and great to drive though personally I prefer the previous shape SL (I have both).

    A better option would be the SL350. ABC was an option so it's one less thing to worry about and economy will be better. The 0-60 time isn't hugely worse either.

    Personally I think 5k for a Cat C is a bit rich too depending mileage.

    Does cat c or cat d history have any effect on insurance levels ?

    A mate had a Cat D something or other. He said it made no odds on the insurance, but you're legally obligated to inform any buyer when selling it on.

    But equally, find a insurance company that doesn't play by a vague, arbitrary, and very loaded, set of rules........
