PURCHASE OPINIONS: ML 350; 500; 55 AMG

[acapulco36]

I am considering the purchase of 1 of the below vehicles, please check the
points and pass any opinions ( from experience preferred ) All are within the
same general price range pre any haggling on my part: 11,000 - 13K AMG

1> ML 350; '03 blk/blk xenon lts, clean 84K miles < Calif car >

2 > ML 500; '02 des sil/ java; 89K, ** vehicle is from Pennsylvania so it does
have under frame corrosion. NO corrosion on door panels, doors,
window seals etc. that I can see. Have photos of under frame doors
etc, so going by photos at this point.
I like this >>> M5 lux pack wood steering, xenon, sport pack,
park assist etc.

3 > ML 55 AMG; 70K; '01 des silver / blk; ( 13,000.00 ask ) ( Calif car )
features of ML 500, but not a '02 so missing all the up-grades.
mirror flashers, up graded consul, and whatever may be internal
upgrades we do not see, etc.

I currently have a '98 / 145K zero problems. Plan to use the '98 in different
local, and what ever I purchase here. I do not have to drive any distances
to work etc daily. So mpg is not a real issue. The 55 has a higher Nada value, but as mentioned not the upgraded signals, interior etc.

Any ML owners on the East coast or snowy areas that have 6,7, 8 year ML's,
I would really like your thoughts on the rust issue that concerns me. And if
you have had rust on the body, panels etc from the snowy weather.

Thanks
