I say go for the celica, girls love that car and its way more unique looking than the prelude. Plus the celica is smaller and "cuter". I myself own a 94 vtec prelude and have driven my friends 97 prelude many times. I also drove my friends 2000 celica and to tell you the truth, I really like the celica. here's a list of things I liked about each car:

Prelude:
looks clean and aggressive
lots of extra interior room

Celica:
insanely unique sporty look
cosey economical interior

from personal experience toyotas are the most reliable cars ever, my mom's toyota minivan 350k miles and still running strong untill I busted the clutch trying to learn how to drive a standard, so we just chucked the whole car since it was old and ugly haha.
