1982 280 CE - Whats it worth?

[Antony thompson]

I have a 1982 Mercedes 280 CE (W123). It has covered 99,000 miles and has full service history.It is in immaculate condition inside and out ,with no rust externally and the interior is complete and not worn.I have no idea how much to insure it for on a classic policy - can someone give me an idea of how much it should be insured for ,and also how much it would be worth in a real world sale - as I said I dont have a clue as to it's value ,and info on these models seems hard to come by.

Any info/advice would be greatly appreciated.

Thanks ,

Antony
