After finalizing, I decided to figure out the actual registration fees for the Model S in Missouri because the number on my pre-MVPA didn't look right.
If you have your car registered already, please comment on what you actually had to pay.
Here are my initial findings:
Fees due at initial registration only:
$8.50 title fee (http://dor.mo.gov/motorv/buying.php)
$2.50 title processing fee
Fees due at initial registration and every year after:
$3.50 1-yr Special fuel decal processing fee
$75.00 1-yr Special fuel decal fee (http://dor.mo.gov/motorv/decals.php)
$3.50 1-yr registration processing fee (can also pay $7.00 for 2 year registration)
$21.25 1-yr registration fee for 12 - 23 taxable HP (can also pay $42.50 for 2 year registration) (http://www.moga.mo.gov/statutes/C300-399/3010000070.HTM section 3)
Total due at initial registration
$114.25 or $139.00 if registering for 2 years
Total due yearly
