Related question: tyres. I have the previous CLK (320 Cab) with
factory-supplied Pirelli 6000 tyres.
One tyre loses pressure over time, say 5 psi over a few weeks. Another
loses a little pressure over time, though still noticeable.
The dealer has tested and says there is no leak.
I am sure I never had this problem with Michelins. Even now, on my 190E it
doesn't happen -- Michelins all round.
Other than that, lovely car. Sometimes I wish I had paid the extra GBP 5000
to get the then available 430, but I do only 5000 - 6000 miles p.a. in it,
so would have been a waste. For me the drawback of the new CLKs is the lack
of a 'vertical' star on the bonnet.
