Thoughts on a 14 Sport package with 19k miles

none of the above, go under the for-sale section on here; ton of low mile cars for way cheaper/cleaner.

there is a 2010 40th with under 10k miles for a good deal, many cars with under 20k miles on here too.

buying private > buying from a dealer (talking used), save thousands, know who the owner was, get a much cleaner car which was cared for by a fellow Z enthutiast - for all you know the dealer got their cars at the auction or the previous owner was DJ db clutch dropper.

In personal experience when buying a performance car used - private sale is the better choice, so much more to list - but you get the point, if you are buying cash - go private. Don't buy into the whole 'oh if you buy from a dealer you get peace of mind', nope. Unless the car is under factory warranty the dealer will tell you to pound sand if something goes wrong.
The only reason to buy from a dealer is for the ease of financing, and at that point you might as well buy new.

+1 on that. I toyed with the idea of getting another 370 for tracking/drifting, and there are better deals out there. Not sure where OP is located, but CraigsList (SoCal) has quite a few for around 20k or under with less than 30k miles on them, clean titles, and in excellent condition. Only potential downside is no warranty.
