I'm looking at a 2009 G37, and it has 148,000 miles on it. Is that too much, and before I buy, is there anything specific I should look for?

 

IMO you could probably find something with lower miles for not too much money, but it’s up to you. If the owner has taken good care of it and has proof and CARFAX looks good you can still get many more miles out of it. For things you should look for the biggest things I’ve learned are if it has had the galley gasket issue fixed or not, and if the sunroof works/if it’s leaky (you can tell because after it rains the passenger side floor will be wet). I’m also looking atm so that’s what I’ve been focusing on.
