I believe the ID.4 is pretty much the same car as the Audi Q4 etron. The deals for those on here seem better than your monthly with nowhere near $5k down.
Have you checked with a broker on here or looked in the Marketplace for the latest ID.4 and Q4 etron deals?
Since you’re a super supporter, you can look up and then change the RV to account for the extra 7500 miles and this should give you a baseline to target.
Quite a few data points in the LH Marketplace. Are you sure your wife needs 15k?
When you go in the LH Marketplace you can filter for the results. For this I put in NorCal as the region and VW for brand and all sorts of broker offerings populate.
You can also do California and I imagine it’s going to be mostly the same result.
