Contract ticker (RANGE ROVER) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Token._takeInviterFee(address,address,uint256,uint256) (#937-974) performs a multiplication on the result of a division:
-curTAmount = tAmount.div(100).mul(rate) (#969)
Token._transferStandard(address,address,uint256) (#976-1012) performs a multiplication on the result of a division:
-_takeDestroyFee(sender,tAmount.div(100).mul(_destroyFee),currentRate) (#988)
Token._transferStandard(address,address,uint256) (#976-1012) performs a multiplication on the result of a division:
-_takeLiquidity(rAmount.div(100).mul(_liquidityFee)) (#991)
Token._transferStandard(address,address,uint256) (#976-1012) performs a multiplication on the result of a division:

Token._transferStandard(address,address,uint256) (#976-1012) performs a multiplication on the result of a division:
-_rOwned[recipient] = _rOwned[recipient].add(rAmount.div(100).mul(recipientRate)) (#1008-1010)
Token._transferStandard(address,address,uint256) (#976-1012) performs a multiplication on the result of a division:
-Transfer(sender,recipient,tAmount.div(100).mul(recipientRate)) (#1011)
Consider ordering multiplication before division.

Token._takeInviterFee(address,address,uint256,uint256).cur (#945) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
