well, I guess it could depend on your credit and your debt situation...if you have good credit and get a low rate and plan to keep the car for more than 3 years, finance it. The idea is that you can make more money on by investing than you would by paying cash(I understand this may not be true these last 2 years)...it comes down to the fact that a car is not an investment...also if you have other debt like credit cards or other cars, pay off the highest balances first...if you have cc debit and 4000 to put down on a car, pay off the cc rather than put the money down...you'd save a bundle in the long run...enough of money management preaching...my 2 cents I guess
I am just wondering...did you think that a $33,000 car would compete well with a $55,000 car? If you had the means and the desire to get a car in the class of a 530, why did you even bother 'going cheap' and getting an IS300? That is like saying, "I can't believe I wasted my money on this civic, I should have bought an IS300". They are in two different classes IMO.
