Yar there is a clear diff between santro club and santro prime....santro prime has BLACK BUMPERS...NOT MATCHING...Santro prime has NO WHEEL CAPS...santro prime has NO MUD FLAPS...and i think santro prime had no FF STEREO....Moreover santro exec is a different story...exec has ps, pw, front n rear chromed grill, rear spoiler,digital clock...and may be one or two more features...
