Need help with buying or leasing a 370z please!

[cjh156]

Ok guys so I'm looking at buying or leasing a 370z and I need some help. I'm 18 and I know my needs for a car will be different in 3 years so I looked into leasing, only problem is that I'm going to have to put at least 3-4 thousand down to even get the payments where I want them(350?) which is probably even under estimating it. I then started at looking at maybe buying a used 2009 370z for around 26,000 and just taking a loan out for 15,000 from my credit union for around 350 a month (perfect!). Do you think I could sell it in 3-4 years and still be looking okay financially? Leasing is just looking really grim right now. what do you guys think? any thoughts would be great thanks!
