You could approach tenants to redo leases more in your favor in exchange for making repairs for them.You want clean slate where they are not constantly referencing what landlord did in the past regardless of what lease said.If there is vague language in the old leases that could be misinterpreted you likely want to redo them or add an updated amendment to the lease clarifying those sections.To a person mentioning if it's in the lease it's valid that is simply not true.

I'd amend your lease to specifically state you are not responsible for damage to their vehicles, assuming such a clause is permissible in your state.

I had a wholeseller show me the original signed contract but "forgot" to show me the amendments that were added.Talk to the actual owners. 

I would write up a contract amendment that specifically spells out the damage and nature of repairs.

I think you'll see most of the older (still active) HOAs without that provision attempting to amend the CC&Rs to include it.
