It’s 9% off MSRP, which is a good deal on a 2018. Find out what they are charging for doc fee, acquisition fee and MF. If they are high, there may be some wiggle room. Also, the rebates are higher on the T6 Momentum, so if you can find one of those close in price to the T5 awd one and can get 9% off MSRP , then you might come out lower.
Your deal is a good one. But, make sure to check out for other charges. Also, you can get some quotations for other dealers online and compare it to your deal.
