With 3drs, saffs, 500s, and escos if you already own a nice one hang onto it, and if you dont then I would not pay the prices they command now, far better cars out there for a lot less money. You are paying a hefty nostalgia premium at the moment.
But if its a dream car then its only money and if you have it spare then treat yourself if the right one comes along. Only buy the best though as the mint parts needed to refurb a rough one are very hard to find
