I bought one with 19k on the clock and bought my current one with 7794 on the clock. 224 miles is nothing to worry about at all. If you like the car, buy it. If something goes wrong you have a warranty.

Frankly for a little more money you should buy new. Improperly broken in Z cars burn oil like crazy. Plus as you know the clutches on those cars are probably abused. I broke my car in for 1,500 km (Canada) and went thru 2.5 litres of oil during that time. I changed the oil to synthetic and have not used an ounce of ol in the past 3 years. My clutch is like new and I change the clutch fluid as soon as it darkens slightly. Strict and complete maintenance on these units will provide you with trouble free driving. The only used 370Z that I would buy would be my Mom's if it were an automatic!

I quit buying new cars years ago. The depreciation in the first couple years is insane. I always buy manuals and never had a problem with clutch wear or oil consumption. I had 2 Hondas and now the Z. The Z was a 2010 bought in 2012 with 12K on the clock. Knock wood, I haven't had to do anything but normal maintenance. Doesn't use a drop of oil. The only car I have had problems with is the BMW I bought new. Biggest piece of crap. Reminded me of American cars from the '70s.
