Irwin think twice before you sell your car, after all, they really aren't worth that much. So unless you absolutely need the extra money for a down payment, I'd keep it.
I made the mistake of selling my perfect, all original 1969 "Hemi" Super Bee back in 1975 for $2,400 just to make a bigger down paymet on my first house. As it turned out, I think I lowered my house payment by about $7 or $8 a month, which made it $201 per month.
