Not sure if purchasing a 944 for an investment is a good idea
.
Passion of ownership, driving experience, performance/value for money are IMHO reasons to get one.
I purchased a good one 8 years ago and have spent more than the purchase price since to keep it in really good fettle, as I am sure other owners have.
(My agreed insured Value is £14,000 to be upped to £15000 next month!)
Air con is an option but on older models may well need re-gassing to latest spec (£500+)

look on Pistonheads.com for Porsche 944's for sale (some at near £16,000 !)
This Forum (obviously) and possibly PCGB (which I did join in 2004 same time as TIPEC but left some years ago
) although I believe you may need to be a member to use their forum!
FWIW a copy of a previous post :-
These cars can be expensive to get into tip top condition, not likely to get your money back when sold; so are you looking get one you intend to keep for a long while?
I started looking into my Porsche ownership in 2004 and had books out of the library and test rides/drives in numerous models eg 911 968 928 944 but started with a reasonably priced 2.7 944 to see if I liked the Marque and Model. (That car is the ONLY car I actually sold for more than I paid for it - apart from Belts/rollers for peace of mind!)
Within a few months I hankered after more Power/Torque & purchased an S2 (Cab).
The difference in all the 944 models needs to be tried as the Cab road handling was not so good as the 2.7 Coupe (naturally!) but great for wind in the hair motoring if you like that sort of thing.
As mentioned in previous post it would make sense for you to get drives/rides in the other models.
My progression of 3 x 944's is shown in my signature resulting in the last 8 years enjoying a tastefully tweaked 199MY Turbo.
Good luck with your search, spent Months rambling myself during the 1st 2 years (2004 to 2006), still rambling on.......
