There is no difference between the doors on the Blista and the doors on the Deluxo.
Please point me to the confirmation from Rockstar that they modeled the Blista after a DeLorean. There's no friggin way! First of all, the Blista Compact is just that, small and bubbly. Where have you ever seen a 'bubbly' DeLorean???? The Deluxo has a narrow front, slanted back and NO CURVES. Just like the DeLorean.
