built this one recently - Lego "Grand Prix Racer" (Technic). its the largest technic I have. Y
ou can get a sense of the size compared to the other lego sets on the left of it & the model cars below which are 1:18 scale.
to the left are the lego "Black Champion Racer" and the red "Pull-back Racer".
Two feet long (box says 56 cm length or something), has working swingarm suspension front and rear, detailed engine parts, working differential steering and adjustable gurney flap [by a gear set].

luckily i had a spare display case around, so i use that to store any sets i build. i would suggest having something made to keep your lego city intact.
