I have an '87 4000 and am looking to upgrade to a '90 to '92 100,200 or V8. would appreciate any brief reccomendations. I understand the v8 requires a lot of maintenance, but performance seems good w/o the trouble of a turbo. I've driven 2-both slush boxes. Seem to run $9 to 12K or so regardless of the model--in Seattle area.
