Last time I checked my Trans Union credit score it was +931 out of a possible +934.
One other thing to try is use an interest only line of credit to buy your car. I have one as my 1st lein on my mortgage. on a 10k loan you may only pay 72$/mo for this 10 k, which gives you xtra money to apply to the principle. as your principle goes down so does your payment, but if you end up short of money in a month, you arent stuck with a 250$ car payment, howver as your balance gets down to 5 k etc.. your interest payment is very small. this is how I went about paying off a 90k mortgage in 4 yrs.
