Go for it, do not listen to the doom merchants, they are probably sales people trying to sell you an expensive aircraft for a fat commission.
If you are wise you can have a great airplane for litttle money and low operating costs.
As all the experts say an old G2 or G3 is virtually worthless. so:
1/ Buy the best ship you can find with a new 72 month inspection and landing gear with at least 5 years on it and engines with 5 years at least to mid life. Cost? peanuts
2/ Employ a good experienced engineer (do not rely on organisations)
3/ Buy another aircraft for spare parts.Cost? less than peanuts.
You will have all the spare parts you want together with spare engines.
One of the biggest expenses with operating aircraft is the engine overhaul reserve. This way you do not have this expense.
For 5 years put gas in it, keep it serviceable with your mountain of spares and put a sticker on your bumper "At least my airplane is paid for"
Seriously do it and good luck. I may even join you and do the same
