My GF and I bought ourselves two old but good MB's last year (financially very attractive company cars due to Dutch tax rules). Her's is an 88 w201, mine's a 87 w124 diesel, both have around 50,000 miles on them. Their 80+ yo owners mostly kept them locked in the garage. They're in matching willow green with pine cloth interiors ;)
I began noticing a bit of a wobble at lower speeds recently, so I mentioned that to my mechanic when I brought it in for its service. It turned out that 1 of the rear tyres had developed a bulge (prelude to a blowout). The tyres on that car, although they had lots of tread, apparently were 12 years old. I googled around a bit and found that replacement by 6 years is advised.
I replaced all my tyres today and I just checked my GF's car: Two 1996, one 2001 and one 1988 (!) tyre. The spare wheel was also a 2001.
It seems I'll have to replace hers as well since this seems pretty dangerous to me now.
I wonder if there are other points that should be checked extra on old cars with very low mileage that spent most of their lives in the garage.
