That $5000 seems like includes down payment which you do not want to put in. I’m also in the Bay Area, and dealers here don’t give out good numbers upfront. You should try to get some quote from socal, and compare them.
I think down payment is about $3700(includes first months $430 with tax). Thenafter, Acquisition fee: $925; Registration, $366; Weight Fee: $80; County Fee: $21; e-filing: $29; Smog: $20; Doc Fee: $80; Batter: $7.
all combines to $5000 with tax.
You should not put anything down. Guess you are in a hurry, but try to get some quote with other dealers and have them compete with each other( yea it’s a lot of work) but if it’s my money I’d think it’s worth to save a bit more.
