My friend selling his 99 Gs300 dashboard says 120k however his carfax and autochecks says car miles are inconsistent, last time car miles were reported correctly was last year 5/05/2012 at 210K. His Gs300 runs very good without a problem. He service timing belt and water pump with oem parts from sewell in october, new oem spark plugs oem breaks done about 2 months ago. He just recently drove car to montana and back without problems. He never ran a carfax at the time of purchase this he recently discovered. DMV said it's legal to sell car but to mark box that states miles are inconsistent.
Body is straight ill say 8/10
Interior 7/10 carpets needs to be washed
Radio pixels are bad.

He's estimating car has 220K(adding 10,000) since last accurate reading.

how much should he ask?

 

he can also contact the DMV to update the records

He should recheck the reports again to see if they've been updated.

you can do it here for free (autocheck and carfax):

with that many miles i would offer him 3500-4k... gs400s go for like 4k-7k with around 170k miles

 

^^ agree. $3500-$4k seems reasonable if its as nice as you say it is. Pictures would certainly help.
