Need some decision help

[supra_rulz]

here's the story:
i have a '88 supra silver exterior, maroon interior (eww) with the 7mgte. it runs "fine" but lately i've been noticing that its using coolant and oil. i've always wanted to do a 2j swap so i figured now's the time to do it. i went to the "bank of mom" for a loan (trying not to sound like a spoiled brat)and got approved so now i'm sitting on total of 5k. at first i thought this would be enough for the 2200 2jzgte + 1500 labor + 1300 in other parts (bell housing, throttle cable, motor mounts blah blah blah). now it sounds like it'll be alot more than originally expected. i was then just looking around craigslist and found a '89 supra with a 1jzgte with one-off custom hood, shaved wing, emblems, and wiper, custom "smokey granite mica" paint, super rare Advan wheels, lots of new drivetrain parts, upgraded suspension, brakes and a "few loose ends" to tie up. (have to figure out exactly what those are) the cost of that is 5k flat. it has a decent amount of upgrades excellent exterior and interior condition, unlike my car with is only okay condition and mostly stock. the reason i am even considering the new car is because it has the interior color that i desperately want (grey) and targa top. i really wanted a 2j but not sure if my wallet is up for that. so now the question is do i keep both cars, save again and swap the 7m to 2j? or sell the 7m and swap the 2j into the 1j car?
i know that was alot to read and most of you could care less but any input would help in making my decision. thanks.
