is it hard to refinance?

[goose3500]

I have been in the market to purchase a vechicle for sometime now, I just reached 600 on my EQ with mostly every creditor in the DC metro area checks.  I talk to my CU on saturday and they told me i needed to reach at least 620 to qualify for a regular car loan and must take in account my credit history including all my lates.  I was wondering if not approved by them and i have to get approve with a high apr is it hard to refinance when my credit is a better like 680 or 690.

I can only speak from my own experience.  I refinanced from a 10.35% loan to 4.15% when my scores were in the 640-680 range.  I got a special promotional rate from a CU.  Paying the auto loan on time for 6 months and keeping my CC utilization low raised my scores 25-45 points in six months.
