If you want a car where your fat ass can fit
buy a cadillac eldorado.
This one for example: http://saskatoon.kijiji.ca/c-cars-vehicles-classic-cars-1969-cadillac-eldorado-W0QQAdIdZ50002641
$4.000 for the car
$2.000 for new paint
$5.000 new interior (leather, digital dash etc)
$3.000 other small fixes (if oil is leaking, new airfilter etc)
$2.000 new stereo
$16.000 for a nice restored cadillac eldorado.
and then if you want you can put some 24s on it if you have money left.
peace
