Which classic model porsche 911?

Just to add a little to what's been said... if you are looking for collectibility, the key issue will be the rarity of the car. Also, how desirable it is to a Porsche fan (ie, a factory 930S slantnose with color to sample hot pink would be very rare, but would only command a higher than normal price to a person that really wants a hot pink slantnose).

Additionally, for investment purposes, a car that is all original is best. A restored car is ok too, but will generally need large amounts of documentation regarding the restore in order to come close to matching an all original car.

So, with that said... the already mentioned 911RS of 1973 would easily be the most desirable of the classic 911 automobiles. But they are quite expensive and can be difficult to track down one that is for sale.

Similar to the 911RS, and likewise produced in smaller numbers (compared to the regular 911s of each era), you would have the 911RS America of the early 90s and the 3.2L 911 Club Sport of the late 80s (there is also the 954/911SCRS, but this is even less realistic to pursue than the 911RS).

The Turbo Carreras are seeing some appreciation in recent years, with the '78-'79 930s being the cream of the crop (the earlier cars that came without the intercoolers are also good; the earlier and later cars would be less desirable by comparison). The 965 Turbo had a few very rare versions that would be good for resale. The has been a revival of interest in the 930S (factory slantnose cars) in the last couple years (but make sure it is an actual factory version, and not an aftermarket conversion).

Any of the 911S long hoods would be very desirable. All of the early (1973 and earlier) long hood cars are seeing good increases in value, but the 911S is the rarest and will always demand the best price.

"Best" can mean different things to different people. You need to ask yourself if this is going to be purely an investment, or if it is about reliability or, most likely, a combination of both. I personally would look for Porsche's, specifically the 911S, between the years of '71 and '74. The early productions (think late 60's) should probably be avoided for obvious reasons (first gen. bugs) Also forget the late 70's models as I've been told they've had reliability problems most specifically with emissions. All in all, just keep doing the research. I'm sure you will be treating this as an investment. Check ownership history, watch for rust, and as a rule of thumb think early 70's and before - they're holding value, later models aren't.

Jack is on the right trail. Other cars in the 25-35 range to look at are 930 turbos (theyre appreciating right now), or if you want to spend more (and if you like them, im not huge on them), 930 slantnoses. 993 Turbo S's are appreciating, and are very fun cars. Theyre pretty expensive though. 73 RS's are awesome, but very expensive. Lotsa classic racecars are good investments too, and some can be had for fairly reasonable prices.

What's the budget?

If unlimited, go with a 1973RS.

If around 40k, go with an early 90's RS America

If around 30ish, get a 1989 Carrera (not a 4), with a G50 transmission.

If around $20k, get an early '80's SC

Good Luck

What's you budget?

I would look for a 911 SC Targa, the targas are great and they don't have the bad Turbo the older ones had. Or a Plastic Window Targa, there rare, and particularly nice.

911S, maybe early 70's. Überclassic.

Or if you really want to drop the bomb, see if this one is for sale!
