I'm thinking of selling my 620, 1996, Jet Glo, not mint but V.Good condition.

Does anyone know what sort of value it has?

Thanks

I generally do a search of completed listings on eBay when trying to gauge value. Doesn't look like many of the 620s on eBay have moved recently; people asking more than buyers are willing to spend.

The only ones that actually sold were:
2008 MG: $1200
1976 Burgundy: $2475

My hunch for yours would be somewhere in the $1200 ballpark, +/- a few bucks.
