Being a new car buyer with no credit, the bank would probably want me to have 60-80% down then finance the rest. If a GS430 is worth $13,000 in good shape today, then I should have $7,500-10,000 saved up. That way I don’t finance too much and risk a catastrophic interest rate on a long-term loan.
I’m getting my $1,500 from the Accord when I hand it over tomorrow (Should have been today but the service dept. apparently closes every Sunday). Assuming they’ll have depreciated to $11,000 across the board by the time I’m ready to buy, I should have a good down payment, like $7,000, in five months. That’s basically January of next year (February if I travel for Christmas).
