I am 28 years old, soon to be 29 and live with my girlfriend who I believe is the one. I have an opportunity to buy a brand new mustang gt, a car that I have wanted long before I could drive. I have always settled for cheaper sports cars because I could not afford the ones I wanted. I just bought a 2013 mazdaspeed3 I'm November of last year as my last fun car before I settled down. My girlfriend is going to finish her masters degree in the spring and start looking for jobs so we can take the next step forward in our relationship... Buying a house! I have been saving plenty of money over the years, more than most people my age. Putting down what I have saved up towards a house of roughly 400k would make my payments roughly 1700 a month between the two of us. I currently owe 8500 on my Mazda, trading it in on the Mustang and putting down an additional 4k that I didn't budget for in my finances this year (gift money per say) would have me with a loan of 14k, raising my payments an additional 80 dollars a month. The difference between is about 10k between the 4k down and the extra 80 a month over 5 years. This is 10k that couldn't be applied towards the house which over a 30 year mortgage is a "$1,300". My other issue is that I car hop alot, I have had 6 cars in 12 years. I know I would be happy with this car but it's also not as practical as my hatchback now especially if I plan on having kids a few 2-3 years down the road. My parents think it's a horrible idea and think I should keep the money for the house my friends say go for it as this could be my last chance to have fun before the minivans and life takes over. On a side note my girlfriends mother has also said she would match what I put down and it wouldn't be at least another year before we would even start to look to buy a house.
