Well both are awesome, the only difference being that joy is 1000cc while Exclusive is 800cc. joy is offered with body coloured side mirrors. Rest everything is same, the body and all the parts, except the engine. While in exclusive and exclusive LS, LS has more features like a clock, powered windows, powersteering (i guess) and much more!
For all i know Get Joy, its locally made, parts are available EASILY at plaza karachi and it is an awesome car Great mileage and great pick. Excellent performance and 10/10 drive comfort.
Just a point that i want to raise is that if you want to get a used one better get it checked by a mechanic (an expert on joy) and then buy on his recommendation. Most people have a hard time maintaing their car and they usually sell out dump. So beware of that
Thanks
and Stay Tuned
