dealer在quote里给了几个奇怪的费用是不是坑

今天找bmw要了一下3系finance的quote，本来是打算pay cash，但是想用他们的college grad program。价格就按照msrp卖，还有几个比较奇怪的费用，感觉像是坑。邮件里这么说的：

Government and Doc fee = $607.42

Accessories = $1,495.00 Cilajet this is a coating that is applied to all new vehicles to protect your cars paint and clear and also protects your investment.

Service contract - $900.00 This covers your brakes service and all the necessary maintenance.

像这些费用是必须给吗，还是可以和dealer说不要。

第一个要给 后面的是dealer卖给你的服务 你可以拒绝
