Looks like a great project car! Let us know if you buy it. A Hemi would be really cool but alot more work than a Mercedes V8. With the hemi plan on fabricating engine mounts, exhaust and possible oil pan work not to mention the ECU and anti theft system issues. Keep in mind that a Crossfire is a Chrysler in name only. Here is a MB 500 V8 on ebay for $2500 A super charged 55 AMG engine would be awesome. I found an almost zero miles 500 engine for only about $1600.
