What is Showcar?
1.
A small engined, budget hatchback (for example a saxo 1.1 or clio) which is usually bought for under £1500 and then receives copious amounts of fibreglass and sound equipment, aswell as neons ,furry interiors, gullwing doors and so on, until £10000 upwards has been spent on said vehicle and it struggles to make it up a slight hill (as there is too much weight for the tiny engine to carry). At which point it can be displayed at a large "meeting" of like minded showcar owners and receive praise and a Macdonalds voucher as a prize.
person 1: why won't that car race me?
person2: dude, why would he race you in a showcar?
