hi. l am planning to buy a 2007 lexus IS250 with $10000 down and an excellent credit line. current l own alexus GX470 bought from the same dealer. how much should l pay at most for the IS250 and at what APR. thanks for your help

if you want pay it off faster and you do not want pay the interest pay the max you have then pay ass much as you can

FREE is the best price for any car

$20000

Switch to a real car and drive the Acura TSX which is much more car for the money unless you still have the crooked l syndrome and like driving a cloud with no control

You could use the GX for a down payment as well. With that, combined with $10K, you should be able to get an IS 350.

You're looking between $31K and $34K most likely.

Forget about APR. You can borrow money cheaper from credit union or use home equity line.
Spend $14.00 at consumerreports.org and they will tell you how much does it cost to buy this car. If you pay <=$500 over invoice (based on demand), you did well.
