even if you welded the doors shut, the panels wouldn't fit... just look at a 2-door vs a 4-door & you can see that the doors on the 2-door are about 10 inches or so longer than the ones on the 4-door... if you wanna make it look EXACTLY like a stock 2-door, you'll LITERALLY have to saw up the ENTIRE SIDE of the damn chasis... and that's just the beginning.... paint work, welding, finishing, interior, seats (need em to fold forward if you wanna take more than one passenger), the actual doors...... by the time you're done, i wouldn't be suprised if the entire side of the car car is warped & wavy
i seriously can't begin to immagine even 1/2 of the amount of work & money it would take to make it look exactly like a factory coupe
it would seriously be the biggest waste of money on an e30............ ever
