The 1992 Mercedes-Benz 600 falls just short of the UK average with a 78.8% first-time pass rate against the national benchmark of 80%, suggesting broadly typical reliability for a car of this age, though only 8.2% have ever suffered a dangerous defect, which is reassuring. These 32-year-old cars are running at a reasonable 97,753 miles median, indicating they've been relatively well looked after, but they average 1.51 failures and 6.0 advisories per test, pointing to the sort of accumulated wear you'd expect in an older luxury saloon.

Budget for maintenance: advisories this frequent suggest consumables and minor components need regular attention, and the failure rate means you should factor in semi-regular repairs rather than viewing this as a care-free classic. Have a full pre-purchase inspection by a Mercedes specialist—these cars reward proper maintenance but punish neglect.
