before going all out suggesting recommendation of cars, let's see how a sports car can be defined through:-
Car manufacture (brand name) - toyota, honda, etc (definitely not LADA, right?)
Car model line- Supra, NSX, MR2, etc
Car engine power, torque, rev-vability, etc, also look at CC. (surely stock 600cc kancil cannot be called a sports car right?)
Car performance (top speed, agility, 0-100 dash, etc) which could be related to the weigh of the car, etc. -In addition, a car with ""all-look, but no-go"" cannot be called a sports car. (if like that, Ah Beng's car with fake scoop, big-ass GT wing, 17inch rim, canard, fake diffuser, interfooler should be a sports car liow)
Pedigree (say, Hyundai Coupe, looks like sports car, but lack repo or racing, track-proven car).
Car layout (FF, FR, Mid engine, etc)
No of seating, no. of door, etc
Wow factor, rarity, oddity value (but how about an uncle-Volvo 240 plonked in with a 2JZ engine?)
Price of the sports car. (if the car is truly a sports car, surely it cant be listed under "cheap sale" or "best bargain" in MotorTrader?)
