your right i have 11 year old duplo and leggo and i have all matchbox cars that ive been keeping. Also a rocking horse and a metal hot rod ride on. they should last too.
We have a matchbox Farrari that was FIL's - so it'd be about 50 years (maybe more).

Also, DH has a Mini that's 48 years old & the body of my step-Dad's FX Holden would be 60 years (not the engine or interior as he's replaced those, but we know people with stock ones).

RF - I'd expect my bookcase to last as it is made to hold books! Its only 3 years old & isn't sagging yet, we shall see.

I expect my sideboard (that came from step-Dad's work when they closed the Brisbane office) to last, but its very plain and office like so I don't know I want it to. Inside it I expect the crokery we got as a wedding present 10 years ago to last, but not the everyday crockery, especially with (soon to be) 2 boys.

Lorelle - clothes horses only last a few years here (close to the beach) before they start getting rust on the plastic coating. Saying that, I've had mine about 10 years, I just put up with the rust and don't put anythng delicate on them.
