Hello,
I‘m a former Merc owner, had a 2014 C250 CDI but got rid of it a couple of years ago because the timing chain had stretched apparently. Since then, been running around in a Reno, which today has developed a nice electrical fault that causes the car to just cut out without any warning. No idea what it is, but thinking of getting rid.
I loved my Merc but the timing chain issue on the OM651 (is that right?) puts me off.
I’ve come across both these CLKs which seem low mileage and within my budget.

I like them both, but would prefer the diesel. Am I right in thinking that it would be the 651’s predecessor in the one above? If so, any major issues I should look out for? Also like the 3.5 petrol, but heard that it also has some big issues within certain engine numbers?
Please can I bow to everyone’s greater knowledge here and ask your thoughts on each? Anything to look out for? Do you think they look okay?
Sorry if i’ve posted in the wrong area. Admin, feel free to move the thread.
First post but long time reader. I’m a Merc fan and eager to get another, within budget.
Many thanks in advance.
