If the miles are over 150,000, then I'll give no more than $1000. If its under, then ill give no more than $1800.

Check Kbb.com for a more precise estimate.

Can't say. You didn't provide enough info. If you were selling it to someone privately I would say $1,500 off the top of my head.

Use the NADA classic car guide, never very accurate though.

Based on your description; probably $2500-3500
