Quoted from EMsInKC:To make them really work right you will need some parts. Bumpers and flippers almost assuredly. You'll need to re-rubber it because the rubbers will likely be dead. The score reels and steppers will probably be gunked uo.
It just depends on the condition. If you get a real basket case you can get it working but it will still look like a basket case. If you get one that has been maintained ok that's different. You'll pay for that though.
Whatever do not buy a multiplayer and especially a Grand Prix. They made a ton of them so there are a lot around but they are complex to work on. A good single player is the starting point and Gottlieb is probably the best because parts for them are more readily available
He meant NOT a Grand Prix!
Agree - Gottlieb, 70s, single player.
I would add, for your first time, don’t try to resurect a trashed EM - rather buy a working one and tinker/fix until you understand how they work. Enjoy!
