<prompt> Human: Ive never purchased a vehicle from a dealership. I bought my dads old car off of him when I left for college and am still driving it now at 27 years old.I have a very good amount of money in savings. I max out my Roth IRA every month. I only have about 300 in bills every month, while my paycheck is about 650week after taxes.I could buy a 30,000 vehicle with cash. this also might mean im not investing my money properly...advice there is welcome too. But I had a professor once say it is harder to save up that 30,000 again. So just take out a loan and pay that with 30,000 you are earning in the future. Does that make sense? Even though you would be paying interest on the loan?Also, just because I can afford that much I wasnt sure if that still makes it a reasonable purchase. I didnt know if anyone here knew of a certain ratio, or percentage, you were suppose to look at on total price compared to salary or something when buying a vehicle. Im considered tight with money I guess, but I have always just stayed away from stupidimpulse purchases. But now I want a different not new, reliable vehicle and was wondering what input you guys would have. Thanks!  <response>: You make about 30K after taxes? I might spend 10K on a car. Thats how much I personally spend on cars regardless of income.
